High Temperature Rectangular Heat Resistant Transparent UV Quartz Glass Plate
Specification & Properties
Rectangular Heat Resistant transparent UV quartz glass plate is made of fused quartz in special industrial technology glass, which is a very good base material. Quartz glass has a series of excellent physical and chemical properties.
The feature of the clear quartz glass is as follows: high purity, strong transmission, strict size control, low OH content and so on. The deep processing would be done according to client's requirements, like neat cutting, fire polish, bending, sealing, polished and so on. OH content can be controlled less than 20ppm15ppm10ppm5ppm2ppm.
Property:
| 1. Incredibly thermally shock resistant (can be taken from red heat and plunged into water without cracking) | 4. Good chemical resistance |
| 2. Low thermal coefficient of expansion (TCE) and high softening temperature | 5. Excellent electrical insulator |
| 3. Optical transmission properties from ultra violet to infra red | 6. High radiation resistance |
