Chemical properties



High temperature resistant



Quartz glass of softening point temperature of about 1730 ℃, can be used for a long time under 1100 ℃, the highest temperature can reach 1450 ℃, short time



Corrosion resistant



Except hydrofluoric acid, quartz glass and other little acids material produces chemical reaction, the acid capacity is 30 times of the ceramic, stainless steel 150 times, especially chemical stability at high temperature, is unmatched by any other engineering materials.







Physical properties of



Good thermal stability



The thermal expansion coefficient of quartz glass, can withstand the severe temperature changes, the quartz glass heated to 1100 ℃ or so, will not burst into cold water.



Pervious to light performance is good



Quartz glass in the ultraviolet radiation to the whole spectrum of infrared wave band has better performance of pervious to light, visible light transmittance over 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80.



Electric insulation performance is good



Quartz glass resistance value is equivalent to ten thousand times of common glass, is an excellent electrical insulation materials, even at high temperatures with good insulation performance



Quartz glass because of the excellent physical and chemical properties, thus has been widely used in electric light source, semiconductor, optical communications, military industry, metallurgy, building materials, chemical, machinery, electricity, environmental protection and other fields.
