Item Feature: 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 contents50ppm, ≤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.
