What is Quartz Glass?
Quartz glass is an engineered material created by melting high purity silica (SiO₂ ≥99.95%) at 2000°C+, forming a non-crystalline structure with unmatched thermal stability and optical clarity.
Unlike natural quartz crystals, synthetic quartz glass lacks grain boundaries, enabling its use in precision optics and extreme industrial environments.

Arc Fusion & Phase Transition
1600-2000°C arc melting in inert gas furnaces to convert crystalline silica into amorphous structure.
Ion Exclusion Leaching
Submerge fused ingots in 18.2 MΩ·cm deionized water for 72hrs, dissolving residual Al³⁺/Na⁺ ions.
Stress-Free Solidification
