Wholesale ZCQ Transparent Customized large diameter quartz tube Quartz pipe vase inner shape
1. SiO2> 99.99% ,high purity quartz tube. 2.Operating Temperature: 1250℃ SoftenTemperature: 1730℃. 3.Excellent visual and chemical performance . 4. without surface coating and infectant. 5. Health care and environmental protection. 6. Any dimension can be made. 7. CE.RoHs SGS approved. Quartz PerformanceChemical properties:Quartz glass is an acidic material, except for hydrofluoric acid
and hot phosphoric acid, it is inert to any other acid and is a
very good acid-resistant material, 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 applied frequency 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 of the ordinary glass times, 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 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 particularly important for users. Company profile
