Fused Silica

 

 

Process Of Production And Characteristic

 

 

The production of fused silica involves the electrofusing of high purity crytalline silica

to form a solid mass whose properties are enhanced as a result of the process. Fused silica in comparison to crystalline silica is purer, and has a lower specific gravity and linear coefficient of thermal expansion. Key characteristics of fused silica include high temperature resistivity and low conductivity, making it ideal for insulative applications, and precision casting mould application. Also, the low thermal expansion and shock attributes of fused silica means that its dimensions remain unchanged under extreme temperatures. Epoxy molded compounds (with fused silica as a key constituent) are used as a base and encapsulating material for electronic circuitry. This application makes use of fused silica low electrical conductivity and insulative capacity, chemical inertness and electrical transparency with respect to electromagnetic radiation.

Applications:

 

 

 

*  In float glass production, Quartz ceramic has been widely used, as a flow control gate, cover plate, brick support brick, seam pressure, etc.

 

*  Fused silica ceramics has the characteristics of dielectric strength, refractory heat at the same time, thus can be applied to the electric heat insulator and light reflector.

 

*  Horizontal tempering furnace at home and abroad is now widely used in roller type hanging glass to replace the old vertical glass furnace toughened system, so as to produce the high quality toughened glass. Horizontal tempering furnace heat can be one of the key factors of success because it USES the fused quartz ceramic roller.

 

*  Fused silica’s linear expansion coefficient is low, its products have high thermal stability, and it has been widely used in black and non-ferrous metals metallurgy.
