Quartz glass is the manufacture of special industrial technology with silica glass, is a very good base material. Quartz glass has an excellent range of physical and chemical properties. Such as:
1, high temperature. Quartz glass softening point temperature of about ***0 degree Celsius
, ***0degree Celsius under long-term, short-term maximum temperature up to ***0 degree Celsius.
2.the corrosion-resistant. In addition to hydrofluoric acid, the quartz glass is almost not react with other acids and its acid capacity is *0 times the stainless steel of the ceramic **0. Especially in the chemical stability at high temperatures, is unmatched by any other engineering materials.
3, good thermal stability. A very small coefficient of thermal expansion of the quartz glass, and be able to withstand severe temperature changes, the quartz glass is heated to about ***0 degree Celsius, placed in water at room temperature and will not burst.
4, the light transmission properties. The quartz glass have good light transmission properties in the infrared spectral band, in the ultraviolet to visible light transmittance at *3% or more, particularly in the UV spectral region, the maximum transmittance of up to *0% or more.
5, good electrical insulation properties. Equivalent to one million times that of ordinary glass, the resistance value of the quartz glass is an excellent electrical insulating material also has good electrical properties, even at high temperatures.
Quartz glass because of the excellent physical and chemical properties, it is widely used point light sources, semiconductor, optical communications, military, building materials, chemical, mechanical, electrical, environmental protection and other fields.
