High-purity Si2o3 fused silica glass stirring rod for stirring

Quartz glass is a single-component glass of silica, which is usually divided into two categories: transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass contains only a few bubbles and is extremely optically homogeneous and transparent. It is made of silicon tetrafluoride placed in a crystal box and melted at high temperature. The content of SIO2 is more than 99.95%, and the content of high-purity quartz glass is 99.999%. . Opaque quartz glass is made of veined quartz and quartz sand, which are melted at high temperature. It contains more than 99.5% SIO2.

feature:
1. High temperature resistance
The softening point temperature of quartz glass is about 1730°C, it can be used for a long time at 1100°C, and the maximum temperature for short-term use can reach 1450°C.

2. Corrosion resistance
Quartz glass has little chemical reaction with other acids except hydrofluoric acid. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperature is unmatched by any other engineering materials.

3. Good thermal stability
Quartz glass has an extremely low coefficient of thermal expansion and can withstand severe temperature changes. Quartz glass is heated to about 1100°C, and it will not burst when placed in room temperature water.

4. Good light transmission performance
Quartz glass has good light transmission performance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, the highest transmittance can reach more than 80.

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

application:
Quartz glass is widely used in electric light sources, semiconductors, optical communications, military industry, metallurgy,
Due to its excellent physical and chemical properties, it is widely used in building materials, chemical industry, machinery, electric power, environmental protection and other fields.
