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.

  • Product Category: Abrasive & Material
  • Key Features:
  • High Purity:Fused Silica has a purity of over 99.9% SiO₂, ensuring minimal impurities and consistent performance.
  • Excellent Thermal Stability: Capable of withstanding high temperatures without significant thermal expansion or degradation, making it suitable for high-temperature applications.
  • Low Thermal Expansion: Exhibits a very low coefficient of thermal expansion, reducing the risk of thermal stress and deformation in high-temperature environments.
  • Optical Clarity: Offers superior optical clarity and transparency, making it ideal for use in optical components and devices.
  • Chemical Resistance: Highly resistant to most acids and alkalis, providing durability in aggressive chemical environments.
