Low price high purity big diameter silica quartz high purity big diameter silica quartz glass tube

1.Fused quartz high purity big diameter silica quartz glass tube available as continuous machine drawn and automatic controlled tubing.

2.This glass had the typical characteriastics of high purity, good spectral transmission, well controlled dimension and lower OH and so on.

3.It serves as the first choice of heat resistant material for halogen lamps, mercury lamps, metal halide lamps and other quartz lamps, used in light, chemical, semiconductor and etc

4.This glass can be supplied in the range of 3-450mm outside diameter, 0.6-20.0mm wall thickness and 10-4500mm length.

5.Exhaust tubes with good CPK are suitable for high-speed streamline production.

6.And further processing of trim cutting, fire polishing, bending and pinching and etc. can be done according to the requirement of customers.

7.OH-content can be controled within 20ppm\15ppm\10ppm\5ppm\2ppm according to the requirement of customers.

Typical Application:

1.halogen,germicidal with ozone lamps,heater etc.
2.mercury,halogen,heater.
3.metal halide lamps and other applications requiring hydroxyl free material.
