fused silica tube
1,High temperature resistance
2,Corrosion resistance
3,Good light transmission performance.
4.high purity
large diameter clear quartz tube sheaths for protecting electrode Sheaths
1, high temperature resistance.Quartz glass softening point temperature is about 1730 DEG C, can be used in long time under 1100 °C
2, corrosion resistanceExcept hydrofluoric acid, the quartz glass almost do not react with other acids occur chemical the acid capacity is 30 times than ceramic, 150 times than stainless steel, especially its chemical stability is perfect at high temperatures.
3, good thermal stability
Quartz glass thermal expansion coefficient is small, can withstand the temperature changes, the quartz glass will not burst when it is heated to 1100 °C, put into the room temperature water
