Physical Properties of Quartz Glass
Quartz glass sheet is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass sheets have a series of excellent physical and chemical properties, such as:
1.High temperature resistance.
Quartz glass has a softening point temperature of about 1730 ° C and can be used for a long time at 1100 ° C. The maximum use temperature can reach 1450 ° C in a short time.
2, Corrosion resistance.
In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially at high temperatures, it is impossible for any other engineering materials. Comparable.
3. Good thermal stability.
The glass has a very small thermal expansion coefficient and can withstand severe temperature changes. The quartz glass is heated to about 1100 ° C and will not burst when placed in normal temperature water.
4. Good light transmission performance.
Quartz glass sheets have good light transmission properties in the entire spectral range from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectrum region, and the maximum transmittance is over 80.
5. The electrical insulation performance of quartz glass is good.
Quartz glass has a resistance value equivalent to 100 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at normal temperature.
