High temperature resistance:
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.
