Product Overview

Fused Silica First Grade (Grade A) is produced using high-purity quartz stone. Through a pickling treatment and high-temperature transformation at 1800ºC in a resistance furnace, crystalline silica is converted into amorphous silica. The resulting product is processed mechanically for iron removal and screening into various blocks, particles, and powders.
