Quartz glass
Quartz glass is a kind of special industrial technology glass, composed with silica, low coefficient expansion.
Mechanical performance
Density: 2.2g/cm3
Bending strength:67 Mpa
Compressive strength: 1100Mpa
Tensile strength:48Mpa
Mohs hardness: 5.5-6.5
Working temperature(long time): up to 1100℃
Optical performance
Quartz glass has very good optical properties, good transmittance in the whole spectrum, especially in the ultraviolet and deep ultraviolet spectrum.
Electrical performance
The main electrical characteristics of quartz glass are high dielectric field strength, low dielectric loss and low conductivity.
Chemical performance
The chemical stability of quartz glass is very good, and does not react with water, salt solution and acids.
Application
Widely used in high temperature resistant equipment in metallurgy and chemical industry, optical and electrical equipment etc.
