Introduction to Fused Quartz Sand

Fused quartz sand is an inorganic non-metallic material produced from high-purity quartz stone sourced from the Lianyungang and Xuzhou regions. It undergoes high-temperature melting, cooling, crushing, and screening processes. Its core component is silicon dioxide (SiO₂), with purity typically exceeding 99.9%. Due to its excellent properties such as high temperature resistance, low expansion, and chemical stability, it is widely used in high-end industrial fields including semiconductors, photovoltaics, precision casting, and electronic information.

Features:

1.Near-zero thermal expansion rate and extremely low thermal conductivity.

2.Excellent thermal stability.

3.High purity (SiO₂ content above 99.95%).

4.Stable chemical properties.

5.Produced with specialized machinery, nearly spherical particle shape, high bulk density, and stable particle size distribution.
