Reasons Why Laboratory Instruments Use Quartz Glass
In daily life, we often come into contact with various types of glass materials. In addition to traditional flat glass, there are glass materials with special properties such as ultra-white glass and borosilicate glass, as well as hollow glass and laminated glass. Common materials. In order to let everyone know more about the advantages of quartz glass, and the difference between it and the composition of crystal, we collected this information and arranged this article, hoping to help.
1. High temperature resistance
The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C. The short-time use temperature can reach 1450 ° C.
In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially at high temperatures, it is impossible for any other engineering materials. Comparable.
3. Good thermal stability
Quartz glass has a very small thermal expansion coefficient and can withstand severe temperature changes. The quartz glass is heated to about 1100 ° C and will not burst when placed in normal temperature water.
4. Good light transmission
Quartz glass has good light transmission performance in the entire spectral range from ultraviolet to infrared, and the visible light transmittance is above 95%, especially in the ultraviolet spectral region, the transmittance can reach more than 80%.
5. Good electrical insulation
Quartz glass has a resistance value equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures. Quartz glass has been widely used in various fields such as electric light source, semiconductor, optical communication, military, metallurgy, building materials, chemistry, machinery, electric power, and environmental protection because of its excellent physical and chemical properties.
