Engineered for Extreme Performance
Our high-purity fused silica solutions are designed to withstand the most demanding physical and chemical environments in semiconductor fabrication.
Thermal Shock Resistance
Capable of enduring rapid thermal cycling up to 1200°C and sudden cooling without micro-cracking or structural degradation, crucial for vertical and horizontal diffusion furnaces.
Chemical Inertness
Provides robust resistance to corrosive acids (excluding hydrofluoric acid) and alkaline environments, preventing process contamination during high-temperature etching and oxidation processes.
Electrical Insulation
Exceptional dielectric strength and extremely low electrical conductivity at high temperatures, ensuring electrical safety in plasma-fused reactor configurations.
