Product Description
Quartz properties:
Chemical properties:Quartz glass is an acidic material. It is inert to any other acid except hydrofluoric acid and hot phosphoric acid. It is a very good acid-resistant material and has better chemical stability than opaque quartz glass. It does not absorb moisture or weather.
Electrical properties:Quartz glass has high dielectric strength and low conductivity. Even under high temperature, high pressure and high frequency, it still maintains high dielectric strength and resistance. There is almost no dielectric loss in the application frequency band. Therefore, quartz glass is an excellent high temperature dielectric. Insulating materials.
Optical properties:Quartz glass has its unique optical properties. It can transmit far ultraviolet spectrum and is a good choice for all ultraviolet light-transmitting materials. It can also transmit visible light and near-infrared spectrum. It is high temperature resistant, has a small thermal expansion coefficient, and has good chemical and thermal stability. , no bubbles, streaks, uniformity, birefringence comparable to general optical glass.
Thermal performance:The thermal expansion coefficient of quartz glass is small, only one-twelfth to one-twentieth of ordinary glass. The standard stipulates that the test piece is burned to 1200 degrees Celsius, and then plunged into cold water. It is not allowed to explode after repeated more than three times. .
