Factory Supplier High Purity Clear Thermal Fused Quartz Silica Glass Plate

Product Description

Product Description

99.99% Pure Quartz Clear Polishing Circular Quartz Glass Sheet 

the quartz plate is a high-performance material that uniquely combines the superior thermal and mechanical properties of quartz with an exceptional ability to diffuse light.This makes it indispensable for high-temperature heating and lighting applications where both safety and visual comfort are paramount.

Product advantages:

1)High Transmittance: Transparent quartz glass has excellent transmittance in the ultraviolet, visible and infrared regions, with a transmittance of over 90% in the range of 200-2500nm.

2)Low Thermal Expansion Coefficient: The linear expansion coefficient is only about 5.5×10^-7/℃, which is much lower than ordinary glass, and it has strong resistance to rapid temperature changes.

3)High Temperature Resistance: It can be used for a long time at a high temperature of 1100℃, and can withstand short-term high temperature impact of 1400℃.

4)Corrosion Resistance: It is resistant to the erosion of most acids (except hydrofluoric acid and hot phosphoric acid) and has good chemical stability.

5)High Hardness: Its Mohs hardness is 7, which is higher than ordinary glass, and it has good scratch resistance.
