Quartz glass is made of silica special industrial glass, is a very good material. Quartz glass has a series of excellent physical and chemical properties:
  1. High temperature: Quartz glass softening temperature of about 1730 ℃, can be used at 1100 ℃ for a long time, the shortest time the maximum temperature of up to 1400 ℃.
  2.Preservative: In addition to hydrofluoric acid, quartz glass almost no other acid substances in the chemical reaction, especially at high temperature chemical stability, is any other engineering materials are incomparable.
  3. Good thermal stability: Quartz glass thermal expansion coefficient is minimal, can withstand severe temperature changes, the quartz glass heated to 1100 ℃ or so, into the room temperature water will not burst.
  4. Good light transmission performance: Quartz glass in the ultraviolet to infrared the entire light band has a better light transmission performance, visible light transmittance of 95% or more, especially in the ultraviolet spectrum, the maximum transmittance of up to 90%.
  5. Excellent electrical insulation performance: The resistance value of Quartz glass is equivalent to 10,000 times of the ordinary glass, is an excellent electrical insulation material, even at high temperatures also have good electrical properties.Quartz glass has been widely used in various fields such as electric light source, semiconductor, optical communication, military engineering, metallurgy, building materials, chemistry, machinery, electric power, environmental protection and so on because of its excellent physical and chemical properties.
  In addition, the expansion coefficient of quartz glass is very small, is one- fourteenth of ordinary flat glass, quartz glass is not afraid of the characteristics of rapid cooling, the quartz glass heated to 900 ℃, and then into the cold water will not burst.
  Quartz glass is divided into linear expansion and body expansion. The expansion and contraction curves of quartz glass are all equal.
  Reversible quartz glass is one of the important properties of quartz glass. The high temperature performance of quartz glass is far more than any kind of glass. Its melting temperature above 1713 ℃, softening temperature 1580 ℃ ± 10 ℃, annealing temperature 1140 ± 20 ℃ quartz glass can withstand more than 1000 ℃ high temperature, short time can be used at 1450 ℃. In the use of high temperature opaque quartz glass can withstand at 900 ℃.
