Transparent quartz tube

Product specifications

The main specifications of transparent quartz tubes produced by our company are outer diameter 3-200mm and length 1200-3000mm. We can also cut, burn, seal, bend, frost, and shape transparent quartz tubes. Strictly controlling the size can meet the high standard requirements of customers. If there are special sizes, they can be customized.

Quartz glass characteristics:

1. High temperature resistance

The hardening point temperature of quartz glass is about 1730℃. It can be used for a long time at 1100℃. The maximum short-term use temperature can reach 1450℃.

2. Corrosion resistance

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

3. Good thermal stability

The thermal expansion coefficient of quartz glass is extremely small and can withstand drastic temperature changes. Quartz glass will not explode even if it is heated to about 1100℃ and placed in room temperature water.

4. Good light transmittance

Quartz glass has good light transmittance in all spectral bands from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectrum region, the maximum transmittance can reach more than 80%.

5. Good electrical insulation performance

The electrical resistance of quartz glass is 10,000 times that of ordinary glass. It is an excellent electrical insulation material and has good electrical properties even at low temperatures.
