Quartz Glass Introduction

Quartz glass is a special industrial technology glass made of silicon dioxide and a very good basic material. 

It has a range of excellent physical and chemical properties, such as:

1. High temperature resistance

The softening point temperature of quartz glass is about 1730 degrees C, can be used for a long time at 1100 degrees C, and the short-term use temperature can reach 1450 degrees C.

2. Corrosion resistance

In addition to hydrofluoric acid, quartz glass almost does not have chemical reactions with other acid substances, its acid corrosion can be better than acid-resistant ceramics 30 times, better than stainless steel 150 times, especially at high temperature chemical stability, is no other engineering materials can be compared.

3. Good thermal stability.

The thermal expansion coefficient of quartz glass is very small, can withstand drastic temperature changes, the quartz glass is heated to about 1100 degrees C, put in warm water will not crack.

4. Good light transmission performance

Quartz glass in the entire spectral band from ultraviolet to infrared has a good light transmission performance, visible light transmission rate of more than 92%, especially in the ultraviolet spectral region, the transmission rate can reach more than 80%.

5. Electrical insulation performance is good.

Quartz glass has a resistance value equivalent to 10,000 times that of ordinary glass, is an excellent electrical insulation material, even at high temperatures also has good electrical performance.

6. Good vacuum

Gas permeability is low; vacuum can reach 10-6Pa

Quartz glass as the “Crown” of all different glass, it can be applied in a wide range:

  • Optical communications
  • Semiconductors
  • Photovoltaics
  • Electric light source field
  • Aerospace and others
  • Lab research
