AMOSIL® is a fused silica which is the amorphous modification of high purity silica. It is artificially produced using an electric arc at 2,000°C. The main feature of fused silica is an extremely low coefficient of thermal expansion (0.5*10-6/K). Therefore these products are particularly suitable for special applications with alternating temperature loading. Through special iron free grinding and subsequent air separation we are able to offer grain size distributions down to submicrons. In addition to our standard products we offer a special grain size optimized grade as well.

SILBOND® is for industrial use, mighty, workable silica sand deposits are of decisive importance. Nevertheless, chemical purity and constancy are not enough in order to apply silica directly as a raw material. In Quarzwerke plants silica sands are thoroughly prepared. The raw material has to pass exten-sive cleaning-, classification-, drying- and iron-free grinding processes in order to produce silica sands, flours and powders. For the production of silica flours and -powders with a defined grain size distribution separation processes are required in addition to iron-free grinding. Quarzwerke are able to produce silica powders with grain sizes down to 1 μm due to a fine-tuned combination of grind- and classification technology. Another refining step is the surface-treatment with silanes or silan-based substances which can be adjusted to the respective application.

Quarzwerke MinMix fillers are made from high-quality industrially washed and processed raw materials. They are homogeneous special mixtures for the production of reaction resin bonded filling compounds. Thanks to the optimized combination of grain fractions based on different raw materials and additives they offer excellent processing properties. Simultaneously the binder quantity is reduced. The maximum filling degree and the curing time depend on the used resin system. Depending on the layer thickness of the product, whether smooth pigmented or sprinkled with colored silica, the resin-filler-ratio can be adjusted at 1:2 to approx. 1:3.

Fused silica products of the product range BRUCAFIL® are particularly suitable for the production of electronic parts and components, when low viscosities, optimized grain size distributions and adapted grain forms play an important role.

Weisser Quarz (White silica) is silica which has slightly been calcined. The silica core is covered by a cristobalite shell. For this reason White silica has the stability of silica but also the high whiteness of cristobalite. Furthermore the grain surface is only slightly chapped
