About Fused Silica Powder Fused Quartz Powder Fused SiO2 Powder:

Fused silica powder with refined quartz powder as raw material, the use of special process modification, makes the fused silica powder, based on retaining the original characteristics, more strongly hydrophobic, thus greatly improving the wettability of fused silica powder, organic solvents in polymer and affinity, greatly improved the fused silica powder filling rate, increase in the dispersion of organic matter, It greatly reduces the viscosity of the mixture system.

Fused quartz or fused silica is glass made of silica in the amorphous form. Unlike conventional glass, it contains no other ingredients and is usually added to the glass to lower the melting temperature. Therefore, Fused silicon has a higher working and melting temperature. Although the terms fused quartz and fused quartz are used interchangeably, their optical and thermal properties are superior to those of fused quartz and other types of glass due to their purity.

For these reasons, it is used in semiconductor manufacturing and laboratory equipment. It can penetrate ultraviolet rays better than other glasses, so it is used to make lenses and optical devices in the ultraviolet spectrum. The low thermal expansion coefficient of fused quartz makes it a useful material for producing fused silica substrates for precision mirror substrates.

Fused quartz is cheaper than zircon, and its density is much lower than that of zircon, so replacing zircon with Fused quartz can reduce the cost of shell-making. The raw material of fused quartz is carefully selected, then remelted by arc, and quartzite is removed, so the impurities are less and the purity is high. So, the stability of paint slurry has never been a problem. The practice has proved that the stability of fused quartz-silica sol coatings can usually be more than one year. Crystallization at high temperatures and phase transition at low temperatures make the casting surface easy to clean.
