Mineral

Rutile

Rutile is a naturally occurring mineral composed primarily by TiO2, it’s also part of the mineral sands group. The main application is feedstock for Titanium Dioxide pigment, welding and other products as special alloys.

Zircon

Also known as Zirconia, due its high thermal resistance and strength Zircon Oxide is largely used in special refractories and Ceramics. The high thermal expansion allows the use of Zirconia for joining of Steel and Ceramic in different types of constructions.

Graphite

Natural graphite is classified as macrocrystalline and microcrystalline (amorphous) depending on the characteristics of the crystal structure. This crystalline composition with a layer structure is precisely what gives graphite its unique combination of material properties, making it suitable for many different fields of application: Welding electrodes.

Calcium Fluorite

Calcium fluoride (CaF2), is used in aluminum-metallurgy, brake lining, glass manufacturing, enamel and glazing frits production, and the production of welding agents.

Mica

Calcined zircon sand

Calcined zircon sand, for use in foundries as coating or for production of cores.

Calcined zircon flour

Calcined zircon flour, for use in foundries as coating or for production of cores.

Sodium feldspar

Ceramic industry. We offer a wide range of soda, calcium-magnesium, and sodium-potassium feldspars. Raw materials are obtained from both environmental restoration works on abandoned sites formerly exploited by third-parties and from recently identified feldspar deposits. After extraction, raw materials generally undergo different and specific treatments to increase their purity and reduce their Fe2O3 content. Finished products are available with different grain sizes to meet all different industrial requirements.

Aluminum hydroxide

Sustainable flame retardant Aluminum hydroxide (APYRAL®) is a ground or finely crystallized, water-insoluble solid. It is used especially for telecommunication and data cables, but also for cables of household appliances as flame-retardants. It is particularly their smoke-reducing and non-toxic properties that make them one of the most popular flame retardants. Because of its very high brightness, it can also be used as white pigment.

Boehmite

Boehmite (APYRAL AOH®) is a high-temperature resistant aluminum oxide-hydroxide, used for production of catalysts for oil industry. It is also used in fire-resistant polymer applications, where it is interesting because of its ecological qualities (it does not contain halogen). It is stable up to 320°C. The high temperature stability allows boehmite to be used in demanding applications for technical components in the automotive or electronics industry.

Aluminum oxide

NABALOX® series of aluminum oxide-based fillers are widely used in foundries, ceramic and polishing industry, and lithium-ion batteries. Due to its great homogeneity, NABALOX® series is well-known for its consistent properties. This gives excellent mechanical, temperature, electric and chemical properties, combined with excellent value for money. Nabaltec offers more than 70 aluminum oxides that differ in composition, surface properties and grain distribution.

Synthetic mullite

SYMULOX® series of synthetic sintered mullites are used in ceramic industry. SYMULOX® is specific for its pronounced homogeneity, with very high level of material purity, and high level of structural micro-crystallization - property which makes SYMULOX® excel in physical parameters, such as resistance to thermal shock.

Wollastonite

Wollastonite is a naturally occurring calcium silicate that is formed from quartz and calcium carbonate at a temperature of about 450°C. The structure of the individual wollastonite particles is determined by the respective geological formation and by the processing technology selected. Depending on the application as a high-performance filler, we produce blocky particle shapes with a low length/diameter ratio (Low Aspect Ratio — TREMIN^® 283 product series) and pronounced acicular wollastonite particles with a high length/diameter ratio (High Aspect Ratio— TREMIN^® 939 product series). Application in plastics (resistance to impact, wearing), fluoroelastomers, e.g. for rotary shaft seals, coatings, anti-corrosion coatings, including water-based EP/PUR. 

Kaolin

Mineral of laminated structure, very high brightness, and coating power. It is a unique and proven industrial mineral, because it also remains chemically inert over a relatively broad pH range. In addition, kaolin is soft, non-abrasive and conducts heat and electricity only to a minor degree. On account of the mineralogical individuality of the different deposits, the kaolins of the company Amberger Kaolinwerke in particular are used with their very special properties in many applications. Used in the paint and varnish, ceramics, porcelain, paper, rubber, and pharmaceutical industry. 

Quartz

One of the hardest natural minerals, chemically inert, with a high melting point. Due to these properties, it is highly valued in many industrial applications, starting from glass industry, foundry, high tension insulators, dental industry, paints and coatings, plaster, engineered stone... The manufacture of quartz flour and fine powders with specified particle sizes requires separation processes in addition to iron-free milling. Using a combination of grinding and optical technologies, we are capable of producing quartz powders with particle sizes of 1 µm.

Colored silica

Innovative filler, produced from pure quartz sand. Each grain is enveloped in a synthetic 2-K-resin dyed with an inorganic or organic pigment as color stable as possible. Available in seven standard granularities and colors and color mixtures. Application: kitchen panels, sinks, engineered stone, colored plaster, road marking paints, epoxy floors.

• Brilliant colors and high light resistance
• Wide range of colors and blends
• Dependable reproducibility
• Safe for aquatic life

White silica

A very special filler that combines the best properties of quartz and cristobalite in the form of a part-cristobalized quartz. In this case a quartz core is enclosed in a cristobalite coating, which gives the white silica the stability of quartz and the high degree of whiteness of cristobalite. Application in road marking paints, facade systems, engineered stone, sinks.

• round grain shape
• density of 2.60 g/cm3
• whiteness (color value Y > 60)
• pressure-stable
• chemically inert

Cristobalite

Cristobalite is synthetically produced for industrial purposes from pure quartz in a rotary kiln at a temperature of approx. 1,500°C. A fractured grain surface, a high degree of whiteness and a density reduction to 2.35 g/cm³ is achieved by the calcination. Like quartz, cristobalite is chemically inert and is therefore popular as a filler in a variety of processes and products. Application: emulsion-bound exterior paints and renders, dental impression composites, engineered stone, silicone sealant compounds, anti-blocking additive in PP and PE film, road markings.

Fused silica

Fused silica is made synthetically in an electric arcing process at about 2000°C as an amorphous modification of quartz. Its most outstanding property is its extremely low thermal coefficient of expansion (0,5*10^-6/K), excellent elasticity and thermal shock resistance. The properties are complemented by a high transformation temperature, high softening temperature, low thermal conductivity, good optical transmissivity, corrosion resistance and a diffusion blocking effect against most substances. Through non-ferrous milling and downline screening processes we are also in a position of being able to produce fused silica granulations in the 1 µm range.

Application: electric insulation, precision casting, electronics, technical ceramics.

Aluminosilicate

Mineral of high thermal conductivity. Chemically inert and resistant to temperature. Mineral with features comparable to aluminum, at a lower price. Applications: cooler in electronic industry, thermally conductive blends.

Feldspar

Mineral of very high chemical resistance; one of the most prevalent minerals in the environment. Most European deposits contain potassium feldspar, sodium feldspar and mixed feldspars. Feldspars are used above all in industrial applications on account of their aluminum oxide and alkali content. Applications: ceramics, glass and porcelain industries, parquet varnishes, dispersive paints.

Synthetic corundum

Synthetic mineral, produced by heating aluminum oxide; hardest mineral, hardness 9 on Mohs scale (diamond = 10). Applications: parquet coatings (high resistance to scratching), decorative coatings, and high-voltage insulators.

Anhydrite

Finely milled and dressed natural anhydrite is a waterless sulphate. It is often formed as an evaporation product from sea water and by the progressive concentration of salt water solutions. Anhydrite forms the stable bottom sediment of gypsum deposits and can be separately mined. Anhydrite is used as a high-performance filler in industrial paints, in construction chemicals, clear lacquer systems and adhesives. Its high degree of whiteness and its transparent properties are of special importance. Applications: glue, transparent parquet varnishes, paints (anti-corrosive, transparent varnishes).

Aluminum hydroxide

Aluminium hydroxide is regarded as being the most important mineral flame retardant in the world and, thanks to its freedom from halogens, it is environmentally friendly and is characterized by its high efficiency as a smoke gas suppressant. Mineral produced from bauxite. Fire-resistant material of high brightness and low hardness. Applications: cables for example made of PVC, textile applications, rubber industry, kitchen countertops, epoxy casting resins...
