Material Description

Quartz is a hard, crystalline mineral composed of silica (SiO₂). Its internal structure forms a stable three-dimensional Si-O network, giving quartz glass its unique combination of:

• Excellent optical transparency

• High thermal stability

• Low thermal expansion

• Strong chemical resistance

• High mechanical strength

These properties make quartz ingots suitable for precision optical components and high-performance industrial applications.
