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.

FAQs of Fused Silica powder Fused Quartz Powder：
Q: What are the main factors influencing the market price fluctuations of Silicon Dioxide Powder (Quartz Powder)?
A: The main raw material for the production of silica powder is quartz ore, whose price fluctuations directly affect the cost of the final product. Changes in market demand, as well as supply from producers, have a direct impact on prices. For example, when demand exceeds supply, prices may rise; they may fall. National or regional laws and regulations on mining and environmental protection also indirectly affect the price of quartz powder.
 
Q: How to compare the quality of silica powder (quartz powder) from different suppliers?
A: Check the supplier's specification sheet for silica (SiO₂) content, as higher purity products are usually more stable. Understand the average particle size of the product and its distribution, different applications have different requirements for particle size. Ask if there is a test report to prove that the product does not contain harmful elements or other unwanted impurities.
 
Q: What are the advantages of buying factory direct silicon dioxide powder (quartz powder)?
A: Some large manufacturers can provide customized products with specific specifications according to customer needs. Directly to the manufacturer helps to establish a long-term relationship, to ensure a stable supply of goods supply manufacturers can often provide more professional technical guidance and support to help customers to better use the product.
 
Q: What special application needs should be considered when selecting silica powder (quartz powder)?
A: Used in semiconductor manufacturing processes, it is important to ensure very high purity to avoid contamination of the chip surface; at the same time, the particle size needs to be very homogeneous. Focus on parameters such as melting point and coefficient of thermal expansion, as they will affect the quality of the finished product. In addition to the basic filling effect, the impact on gloss, hiding power, etc. needs to be considered.
