Sibelite M72

SIBELITE® coarse products are high-purity silica products produced by thermal treatment at high temperature of selected and treated quartz grains. The modified crystal structure “cristobalite” is afterwards stabilised by fast cooling down. A narrow particle size distribution, excellent optical properties, constant whiteness and chemical inertness lead to a highly appreciated raw material in many performing industries, such as silicates, plastics, coatings, precision-casting, ceramics etc.
