Description

Quartz/Silica glass is used where high service temperature, very high thermal shock resistance. Quartz glass is produced from silicon dioxide and is a highly pure material. Melting and refusing of crushed natural crystalline quartz. Clear fused quartz glass features high purity (>99.98% SiO2), good physical and chemical properties, tight tolerances, and low -OH content. Especially low coefficient of thermal expansion of quartz provides excellent stability and resistance to thermal shock over large temperature excursions and wide thermal operating range. Are used for high temperature applications up to 1200°C (2192°F).
