20 um High Whiteness Fused Silica Powder Melted Quartz Sand for Investment Casting
Fused Silica Products
Natural high purity quartz its microstructure at high temperature becomes the amorphous structure of the fused silica.
Is molten particles and silicon powder with high quality fused silica, through special crushing grinding process, the product high purity, controllable particle size distribution.
The main characteristics of fused silica are:
●High temperature resistance, good whiteness, melting point 1750 ℃.
●Excellent low electrical insulation.
●High hardness, high resistance to wear.
●Low expansion coefficient is low.
●Chemical properties of stability, in addition to react with hydrogen fluoride ether and alkali, does not react with any other material.
Photovoltaic materials, electronic materials, refractory materials, investment casting, high voltage electrical insulation materials, paint coating, silicone rubber, special ceramics, advanced materials, fine chemical industry, aerospace and other industries.
