Product Specifications

Product Description

Property:
With very low expansion coefficient, high temperature resistance, good chemical stability, excellent insurability, low and stable ultrasonic delay, the best function of transmission of ultraviolet, visible light and near infrared light as well as the better mechanical properties than normal glass. Quartz glass is one of the best and indispensable raw materials used in space technology, atomic industry, national defense, automatic systems, and the industries of semiconductor, metallurgy, chemicals, lighting resources, building materials, and so on.
The OH contents: ≤50ppm, ≤10ppm, ≤5ppm, ≤1ppm

Applications:
In lighting and heating industries, it is widely applied for halogen lamp, mercury lamp, single-ended lamp, automobile lamp, stage lamp, thermocouple, printer lamp, sleeve for water treatment lamp, quartz utensils and pipes, etc.
