Introduction
Foreign name;quartz glass;silica glass;fused quartz;fused silica ;vycor glasses
Form use
The formation of quartz glass is a result of the high viscosity of the melt. Used to make semiconductors,
Quartz glass
Electric light source, semi-conductive communication device, laser, optical instrument, laboratory instrument, electrical equipment, medical equipment and chemical instruments resistant to high temperature and corrosion, chemical, electronics, metallurgy, building materials and national defense industries are widely used.
High-purity quartz glass can be used to make optical fibers.
With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor production. For example, the Czochralski method converts polycrystals into single crystal silicon; the cleaning bath used for cleaning; the diffusion tube used for diffusion, the grooved boat; the bell jar used for ion implantation, and the like.
definition
Quartz glass is a special glass that contains only a single component of silica. Due to type, process, raw materials
Different from quartz glass, foreign countries are often called silicate glass, quartz glass, fused silica, fused quartz, synthetic fused silica, and transparent, translucent, opaque quartz without a clear concept. China's collective name is quartz glass, which is classified according to the process, use and appearance, such as fused transparent quartz glass, fused silica glass, gas-refined transparent quartz glass, synthetic quartz glass, opaque quartz glass, optical quartz glass, quartz glass for semiconductors. And quartz glass for electric light source. It is absolutely inappropriate to use a simple vocabulary such as "quartz" to name this material, because "quartz" is a generic term for the crystalline state of silica, which is in physical and chemical properties with glassy silica. There is a difference.
