The performance of quartz glass instruments is as follows:

1. High temperature resistance

The softening point of quartz glass is 1750 degrees Celsius, and it can be used for a long time at 1200 degrees Celsius, with a maximum temperature of 1450 degrees Celsius for short periods of time. Capable of deformation processing.

2. Corrosion resistance

Except hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 200 times that of stainless steel. Especially, its chemical stability at high temperature is incomparable to any other engineering material.

3. Good thermal stability

The expansion coefficient of quartz glass is extremely small and can withstand severe temperature changes. Heating quartz glass to 1200 degrees Celsius will not crack when placed in room temperature water.

4. Good transparency

Quartz glass has good transmittance throughout the entire spectral range from ultraviolet to infrared, with a visible light transmittance of over 95%, especially in the ultraviolet spectral region, where the maximum transmittance can reach over 80%.

5. Good electrical insulation

The resistance value of quartz glass is 10000 times that of ordinary glass, making it an excellent electrical insulation material with good electrical properties even at high temperatures.

Due to its excellent physical and chemical properties, quartz glass is widely used in various fields such as electric light sources, semiconductors, optical communication, military industry, metallurgy, building materials, chemistry, machinery, power, environmental protection, etc.
