High temperature resistance:
Quartz glass has a softening point temperature of about 1730 °C and can be used for a long time at 1100 °C. The maximum use temperature can reach 1450 °C in a short time.
Good thermal stability.
As the quartz glass thermal expansion coefficient is extremely small,it is to work in a variety of bad situation.
Good corrosion resistance.
The quartz glass has higher protection performance of corroding, mainly used in surroundings of abominable sours, high voltage and high temperature.
