1. Physical properties
Quartz glass is glass consisting of silica in amorphous (non-crystalline) form. It differs from
traditional glasses in containing no other ingredients, which are typically added to glass to lower
the melttemperature. Fused silica, therefore, has high working and melting temperatures.
The optical andthermal properties of fused quartz are superior to those of other types of glass
due to its purity.
For these reasons, it finds use in situations such as semiconductor fabrication and laboratory
equipment. It has betterultraviolet transmission than most other glasses, and so is used to
make lenses and other optics for the ultraviolet spectrum. Its low coefficient of thermal
expansion also makes it a useful material for precision mirror substrates.

2. Advantage of Product
1. high temperature resistant, Quartz Slab Or Optical Quartz Glass Plate Or Quartz Substrate,
Fused Quartz Glass can work under 1200°C continuously,and in short time can even work
under 1450°C,its softening temperature is 1650°C,and the melting temperature is 1750-1800°C.
2. Corrosion resistant, Except hydrofluoric acid, Quartz Plate Of Optical Grade do not react with
any acid and base except hydrofluoric acid.the stability is
30 tims of the ceramic,and 150 times of stainless steel .
3. Excellent thermal shock stability
4. High transmission to 85%
5. Electric insulation ,it is 10000 times of usual glass
