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.
