High Temperature Resistance
The softening temperature of quartz glass tube is about 1730℃, which can be used at 1100℃ for a long time, the short time use temperature can reach 1450℃.
Corrosion Resistance
Except for hydrofluoric acid, quartz glass almost no chemical with other acid, its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. especially at high temperature chemical stability, is incomparable to any other engineering materials.
Good Light Transmittance
In the entire spectrum of ultraviolet to infrared wavelengths have good light transmission, visible light transmission rate of 92% or more in the ultraviolet spectrum region, the transmission rate of 80% or more.
Good Thermal Stability
The thermal expansion coefficient of quartz glass is small, can withstand drastic temperature changes, quartz glass heating to about 1100℃, put in room temperature water will not burst.
Strong Insulation
The resistance value of quartz glass is equivalent to 10,000 times of ordinary glass, is a better electrical insulation material, even at high temperature also has good electrical properties.
Main Product
Quartz Performance
Chemical properties: Quartz glass is an acidic material, except for hydrofluoric acid and hot phosphoric acid, it is inter to any other acid and is a very good acid-resistant material, quartz glass almost no chemical with other acid, its acid resistance is 30 times that of ceramics, and 150 times that of stainless steel. especially at high temperature chemical stability, is incomparable to any other engineering materials, with better chemical stability than opaque quartz glass, non-hygroscopic and non-weathering.
Electrical Properties: Quartz glass has high dielectric strength and low conductivity, even at high temperature, high pressure and high frequency, still maintain high dielectric strength and resistance. almost no dielectric loss in the freqency band, so quartz glass is excellent high temperature dielectric insulation material.
Optical Performance:Quartz glass has its unique optical properties, it can transmit both the far-ultraviolet spectrum, which is a good choice for all UV-transmitting materials, and can transmit visible light and near-infrared spectrum, high temperature resistance, small coefficient of thermal expansion,good chemical thermal stability, bubbles, streaks, uniformity, birefringence and comparable to general optical glass.
Thermal Properties: The coefficient of thermal expansion of quartz glass is small, only one-twelfth to one-twentieth times of the ordinary glass, the standard stipulates that the specimen will be burned to 1200 degrees Celsius and then cast sharply into cold water, repeatedly more than three times is not allowed to blow up.
Mechanical Properties: Quartz glass mechanical properties than coin glass and ceramics are better, but the brittleness is poor. The the theoretical calculated strength of quartz glass is very high, about 24*1.3 MPA, but the actual measured strength is tens of times lower than this value.
Airtight Performance: The structure of quartz is very relaxed, even at high temperatures also allows the ions of certain gases to diffuse through the network, including the diffusion of sodium ions for the faster. This property of quartz glass is particulary important for users.
