Fused Silica First GradeHigh 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. I. Characteristics1. Near zero
thermal expansion, extremely low thermal conductivity.2. Excellent
thermal stability.3. High purity (the SiO2 content is above 99
%).4. Chemical properties are stable.5. General mechanical
