Raw materials for the industry

Abrasive Industry

In abrasive production, the selection of raw materials such as calcined bauxite, silicon carbide and zirconia alumina is crucial in order to achieve excellent product quality. Hardness and heat resistance are essential qualities that a material must possess for the manufacture of grinding tools. CREMER ERZKONTOR offers a wide range of raw materials for the abrasives industry.

Products

Raw Kyanite

Minerals

Raw Kyanite is an aluminosilicate mineral. After ore crushing the kyanite crystals are separated from other ore elements by heavy media separation and flotation. Concentrat...

Minerals

Silicon Carbide (SiC) is a crystalline solid characterized by extreme hardness, high temperature resistance and electrical conductivity. SiC is used in many technical appli...

Reactive Alumina

Minerals

Reactive Alumina is a special raw material used in the manufacture of abrasives and abrasive products. It is characterized by its extreme hardness, high strength and abrasi...

Tabular Alumina

Minerals

Tabular Alumina is a re-crystalline sintered alpha alumina with high density. It consists of large (50 – 200 µm), flat, table-shaped corundum crystals.

White Fused Alumina

Minerals

White Fused Alumina (WFA) is a high-purity, white abrasive made from aluminum oxide. It is produced by melting high-quality alumina in an electric arc furnace at very high ...

Calcined Kyanite

Minerals

Calcined Kyanite is produced by calcination of Virginia Kyanite, an alumino silicate. Kyanite ore is crushed, the kyanite crystals are separated from other ore components a...

Zircon Flour

Minerals

Zircon Flour is a mineral powder obtained from zircon sand that is used in various industrial applications. It is characterized by its high hardness, abrasion resistance an...

Calcined Bauxite

Minerals

Calcined Bauxite is produced by the sintering/calcining of low-iron, low-alkali containing raw bauxites at temperatures of 1600 – 1800°C. In this calcination process the hi...

Brown Fused Alumina

Minerals

Brown Fused Alumina (BFA) is a very hard, tough abrasive raw material produced by melting bauxite (an aluminum ore) at extremely high temperatures. During the melting proce...

Chrome Oxide Green

Minerals

Chrome Oxide Green is an inorganic green pigment made from various chromium compounds by heating to approx. 800°C. It can be used in paints, inks and glasses. Due to its hi...

Diatomaceous Earth

Minerals

Diatomaceous Earth is a pale-colored, soft, lightweight sedimentary rock composed principally of silica microfossils of aquatic unicellular algae.
