Quick Details


The types of quartz tube

Quartz tube can be roughly divided into the following kinds: transparent quartz tube 3 mm - 300 mm (diameter) and opaque quartz tube, filter uv quartz tube, color quartz tube, etc. Quartz glass tube is made of silicon dioxide in special industrial technology glass, is a very good base material. Quartz glass has a series of excellent physical and chemical properties.

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.
