300mm Diameter Large Size Transparent Fused Silica Ring
Quartz tube is a special industrial technology glass made of silica. It is a very excellent basic material.
1. High temperature resistance. The softening point temperature of quartz glass is about 1730 ℃, which can be used for a long time at 1100 ℃, and the maximum service temperature in a short time can reach 1450 ℃.
2. Corrosion resistance. Except hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperature is unmatched by any other engineering materials.
3. Good thermal stability. The coefficient of thermal expansion of quartz glass is very small and can withstand drastic temperature changes. If the quartz glass is heated to about 1100 ℃, it will not burst in normal temperature water.
4. Good light transmittance. Quartz glass has good light transmission performance in the whole spectral band from ultraviolet to infrared, and the visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80.
5. Good electrical insulation. The resistance value of quartz glass is 10000 times that of ordinary glass. It is an excellent electrical insulation material and has good electrical properties even at high temperature.
