Physical and chemical properties of quartz tube

Quartz glass tube is a kind of special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as:
1. High temperature resistance
The softening point temperature of quartz glass is about 1730 ℃, which can be used at 1100 ℃ for a long time, and 1450 ℃ for a short time,
2. Corrosion resistance
In addition to hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times of that of ceramic and 150 times of that of stainless steel, especially its chemical stability at high temperature, which is incomparable to any other engineering materials.
3. Good thermal stability
   the thermal expansion coefficient of quartz glass is very small, and it can bear the drastic temperature change. When the quartz glass is heated to about 1100 ℃, it will not burst when it is put into the normal temperature water.
4. Good light transmittance
Quartz glass has good light transmittance in the whole spectrum from ultraviolet to infrared. The visible light transmittance is over 93%, especially in the ultraviolet spectrum, the * transmittance is over 80.
5. Good electrical insulation
The resistance value of   quartz glass is 10000 times that of ordinary glass. It is an excellent electrical insulating material, and has good electrical performance even at high temperature.
Because of the above excellent physical and chemical properties, quartz glass is widely used in various fields such as electric light source, semiconductor, optical communication, military industry, metallurgy, building materials, chemistry, machinery, electricity, environmental protection, etc. (information for reference only!)
