Advantages of quartz are as follows:

1, high temperature resistance. The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1150 ° C, and the maximum temperature for a short time can reach 1450 ° C.

2, corrosion resistance. In addition to drofluoric acid, high purity quartz almost does not react with other acid substances, at high temperatures, it can resist sulfuric acid, nitric acid, drochloric acid, aqua royalty, neutral salts, carbon and sulfur erosion. Its acid resistance is 30 times that of ceramics, 150 times that of stainless steel, especially its chemical stability at high temperatures, which is unmatched by any other engineering material.

3, good thermal stability. The coefficient of thermal expansion of high purity quartz is very small, can withstand intense temperature changes, the high purity quartz is heated to about 1100℃, and will not burst into normal temperature water.

4, good light transmission performance. High purity quartz has good light transmission performance in the entire spectral band from ultraviolet to infrared, visible light transmittance of more than 93%, especially in the ultraviolet spectral region, ~ large light transmittance of more than 80%.

5, good electrical insulation performance. The resistance value of high-purity quartz is equivalent to 10,000 times that of ordinary quartz glass, which is an excellent electrical insulation material and has good electrical properties even at high temperatures.
