Product Description
The softening point of quartz glass is about 1730 ℃. It can be used at 1100 ℃ for a long time, and the maximum temperature can
reach 1450 ℃ in a short time.
Good thermal stability
The coefficient of thermal expansion of quartz glass is very small, and it can withstand drastic temperature changes. When the
quartz glass is heated to about 1100 ℃, it will not burst into normal temperature water.
quartz glass is heated to about 1100 ℃, it will not burst into normal temperature water.
Good light transmittance
Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The visible light transmittance is
more than 93%, especially in the ultraviolet spectral region, the maximum transmittance is more than 80

electrical insulation
has good insulating performance even at high temperature.
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 its chemical stability at high temperature, which is unmatched by any otherengineering materials.
Product use
Quartz glass is widely used in electric light source, semiconductor, optical communication, military industry, metallurgy,
building materials, chemistry, machinery, electric power, environmental protection and other fields because of its excellent
physical and chemical properties

instructions
Precautions for use of quartz glass:
1. Quartz glass products are valuable materials, so they must be handled with care;
2. All kinds of quartz glass have a maximum service temperature, which should not be exceeded, otherwise crystallization or
softening deformation will occur;
3. The quartz glass that needs to be used at high temperature must be wiped clean before use. It can be soaked in 10%
hydrofluoric acid or lotion, then cleaned with high purity water or treated with alcohol. Wear fine gloves during operation,
and do not touch quartz glass directly with hands;
4. Continuous use of quartz glass products is allowed under high temperature, which is beneficial to prolong the service life of
quartz glass and improve the temperature resistance. On the contrary, the intermittent use of quartz glass products under high
temperature has limited use times;
5. Although quartz glass has high thermal stability, it can withstand sharp temperature difference. However, due to the
difference of residual strain and product shape, there are some differences in thermal stability in practical use, which
should be paid attention to;
6. Quartz glass is acidic material. When it is used at high temperature, it should be strictly avoided to contact with alkaline
substances (such as sodium silicate, asbestos, potassium and sodium compounds, etc.), otherwise its anti crystallization
performance will be greatly reduced.
