High Purity Fused Silica Half Round Quartz Glass Rod

High Purity Fused Silica Half Round Quartz Glass Rod

Main Appilication: It service as the material of the bridging rod for single-ended halogen lamps ,optical fiber lighting.quartz fiber and semiconductor silicon chip processing,military industry, metallurgy, building materials, chemical, machinery, electricity, environmental protection and other fields.

Features

1.High purity made of 99.99% pure quartz.
2.Strong hardness, can reach morse level 7.
3.High temperature resistance, can work under 1200°C continuously,and in short time can even work under

1500°C.

4. Electric insulation, it is 10000 times of usual glass.

5. Health care and environmental protection.
6. Any dimension can be made.

7. Except hydrofluoric acid, quartz glass does not react with any acid and base except hydrofluoric acid. The stability is 30 times of the ceramic, and 150 times of stainless steel.
8. High light transmittance , it is different from 85%-95% depend on different spectrum.

9.Excellent thermal shock stability ,Small thermal expansion coefficient,it is only 5.5×10-7/℃.

Attention for quartz rod

1. Do not operate in temperature beyond quartz maximum working temperature for long time. Otherwise, products will deform crystallization or become softening.
2. Clean the quartz products before high temperature environment operation . Firstly soak the products in 10% hydrofluoric acid, then wash it with high purity water or alcohol .Operator should wear thin gloves , direct touch with the quartz glass by hand is inhibited.
3. It is wise to extend the lifespan and thermal resistance of quartz products via continuous use within high temperature environment. Otherwise, interval use shall shorten products lifespan.
4. Try to avoid touch with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.)when employing quartz glass products in high temperature, which is made of acid material. Otherwise product anti- crystalline properties will be greatly reduced.
