1. Near zero thermal expansion, extremely low thermal conductivity.
2. Excellent thermal stability.
3. High purity (the SiO2 content is above 99.5%).
4. Chemical properties are stable.
5. Special machinery production, particle size close to circular, large packing density, stable particle size distribution.
II. Main Areas of Application for Fused silica sand
Quartz nozzle, quartz crucible for steel industry
Shell-making materials in precision casting
