1. Physical properties of quartz glass introduction:

Quartz Glass is a special industrial technology glass composed of a single component of carbon dioxide, because of its low Coefficient of thermal expansion, high temperature resistance, good chemical stability, excellent power insulation, low and stable ultrasonic delay performance, good head UV spectral performance and transparent visible and infrared spectral performance, and has, its mechanical properties are superior to those of ordinary glass, making it a space technology of modern high-end technologies, including the atomic energy industry, defense equipment, and automation systems, as well as semiconductors, metallurgy, chemicals, electric light sources, communications, and light industries, one of the indispensable high-quality materials in building materials and other industries.

2. Chemical properties

Q uartz glass belongs to acid materials, except hydrofluoric acid and thermal phosphoric acid, other human acids are inert, is a better acid-resistant material, at room temperature alkali and salt on the degree of corrosion of quartz glass is also small, so do not rule out the use of quartz glass in these reagents.

2. Optical properties,

1. the optical properties of quartz glass has its unique, it can be transmitted through the far-ultraviolet spectrum, is the best of all uv-permeable materials, but also through the visible and near-infrared spectrum, users can according to needs, the varieties were selected randomly from the range of 185-3500m μ. Because of its high temperature resistance, small Coefficient of thermal expansion, good chemical thermal stability, bubble, stripe, uniformity and birefringence, it can be compared with ordinary chemical optical glass, therefore, it is necessary to work in a variety of harsh situations with a high degree of stability of the optical system optical materials.

3. Use Notes

1. Quartz glass products are valuable materials, use must be handled gently, very carefully; 2. All kinds of quartz glass have a maximum use temperature, use should not exceed this temperature, otherwise it will crystallization or softening deformation. 3. High-temperature use of the use of glass, use must be wiped clean. It can be soaked in 10% hydrofluoric acid or laundry detergent, then washed with high-purity water or treated with alcohol. Dust-free gloves should be worn during operation. Direct hand contact with quartz glass is not allowed. Four. High temperature allows the use of quartz glass products, which is beneficial to extend the life of quartz glass and improve the temperature resistance. On the contrary, the intermittent use of high temperature quartz glass products, the number of its use is limited. 5. Although quartz glass material has high thermal stability, can be handled by drastic temperature changes. But the thermal stability of quartz stone is different due to the different participating strains and product shapes, so it should be paid attention to. 6. Quartz glass is an acid material, avoid contact with alkaline substances (such as sodium silicate, asbestos, potassium and sodium compounds) strictly when used at high temperature, otherwise it will greatly reduce its anti-crystallization performance.
