Fused Silica - Product
Fused Silica
Fused Silica is a high-purity, synthetic form of silicon dioxide (SiO₂) produced by melting high-quality quartz or silica sand at extremely high temperatures. This process yields a material with excellent optical clarity, thermal stability, and chemical resistance. Fused Silica is widely used in various high-tech and industrial applications, including optics, electronics, and refractory materials.
