AB Grade Fused Silica Refractory , White Refractory Materials 99.8% Pure

Fused Silica


Process Of Production And Characteristic


Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000℃) to amorphous Silicon dioxide , then it was classed to different grades by manual and then specially engineered to granular and powder form. Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, it is used in lots of fields of investment casting,refractory,ceramic,epoxy modling compound,fusion bounded epoxy.

Applications:


1. Application in metallurgical industry


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.


2.Applications in electrical industry


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.


3. Application in float glass industry


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


4. Application in glass processing


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.
