Cut or crushed, mono- or multicrystalline: High-purity silicon (Si) is applied in various forms, especially in industry. It is used to coat a wide variety of materials in order to optimise their material properties and produce functional layers. It features primarily in photovoltaics, optics and optoelectronics, semiconductor technology, sheet-glass production and the entire spectrum of research and development. We offer high-purity silicon with purity of at least 4N, cleaned and etched on request.

Crushed amorphous or crystalline: High-purity quartz glass (SiO₂) is used as a raw material for special coatings in optics and optoelectronics, semiconductor technology, flat glass production and in research and development. Our SiO₂ is available with purity of at least 5N – sieved and fractionated.
