Product Description
Fused Silica First Grade (also known as A)
High purity quartz stone in Lianyungang and Xuzhou area was selected as raw material. After pickling treatment, the crystalline silica was transformed into amorphous silica with a small amount of impurity at 1800ºC high temperature in the resistance furnace. After special mechanical processing, screening, iron removal after the formation of blocks, particles and powder products.
Fused Silica First Grade
I. Characteristics
1. Near zero thermal expansion, extremely low thermal conductivity.
2. Excellent thermal stability.
3. High purity (the SiO2 content is above 99.95%).
4. Chemical properties are stable.
5. Special machinery production, particle size close to circular, large packing density, stable particle size distribution.
