Description

1, high temperature.Quartz glass softening point temperature of about ***0 ° C at ***0 ℃ for a long time, a short time maximum temperature up to ***0 ° C, 2, corrosion-resistant. Except hydrofluoric acid, the quartz glass is almost no chemical reaction occurs with the other acids and its acid capacity is *0 times that of the ceramic, stainless steel, ***-fold, especially in the chemical stability at high temperatures, is any other engineering materials are unable to match. 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 ℃, placed in water at room temperature and will not burst. 4, the light transmission properties. The quartz glass in the ultraviolet to have better light transmission properties of the entire spectral band of the infrared, 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 in electric light sources, semiconductor, optical communications, military, metallurgy, building materials, chemical, machinery, electricity, environmental protection and other fields.
