Quartz tubes can be roughly divided into the following types: transparent quartz tubes (outer diameter 1.5mm-300mm), ultraviolet filtering quartz tubes, colored quartz tubes, etc.

Chemical properties

High temperature resistance

The softening point temperature of quartz glassChina quartz glass products suppliers is about 1730°C, and it can be used for a long time at 1100°C, and the maximum use temperature can reach 1450°C in a short time.



Except for HF, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is unmatched by any other engineering materials. .

Physical properties

Good thermal stability

The thermal expansion coefficient of quartz glass is extremely small, and it can withstand severe temperature changes. When the quartz glass is heated to about 1100°C, it will not burst when placed in water at room temperature.

Good light transmission

Quartz glass has good light transmittance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach above 80.

Good electrical insulation

The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good insulating properties even at high temperatures.

Quartz glass has the above-mentioned excellent physical and chemical properties, so it is widely used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, and environmental protection.
