The size of the silica glass rod, the type of
Divided by color: transparent quartz rod frosted quartz rod
At present, we can produce the specifications
Length: 10-1240mm
Diameter range: 2-70mm
Chemical properties
Temperature
Quartz glass softening point temperature of about 1730 ℃, prolonged use at 1100 ℃, short-term maximum temperature up to 1450 ℃,
Corrosion
In addition to hydrofluoric acid, the quartz glass almost no chemical reaction with the other acids, which acid is 30 times the capacity of ceramic, stainless steel, 150-fold, especially in the chemical stability at high temperatures, and any other engineering materials are unable to match.
Physical Properties
Good thermal stability
The thermal expansion coefficient of quartz glass is very small, can withstand severe temperature changes, the quartz glass is heated to about 1100 ℃, into the water at room temperature will not burst.
Good light
UV quartz glass to the entire spectral band of infrared rays have better light transmission properties, visible light transmittance of 93% or more, particularly in the UV spectral region, the maximum transmittance of up to 80 or more.
Good electrical insulation properties
The resistance value equivalent to the quartz glass one million times that of ordinary glass, is an excellent electrical insulating material, even at high temperatures also have good insulating properties
Quartz glass has the above excellent physical and chemical properties, so it is widely used in electric light, semiconductors, optical communications, military, metallurgy, building materials, chemical, mechanical, electrical, environmental protection and other fields.
