Fused Silica Powder Fused Quartz Powder Fused SiO2 Powder
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, Fused SiO2 Powder)
Q: What is fused silica powder used for?
A: Fused silica powders, also known as fused quartz or fused SiO2 powders, are utilized in a broad range of applications due to their exceptional properties. These include high thermal stability, low thermal expansion coefficient, excellent optical transparency, and resistance to chemical attack. They are integral components in the manufacturing of electronic devices, where they serve as substrates for semiconductors and insulating layers. In the field of optics, fused silica is prized for its use in lenses, mirrors, and windows that require superior transmission of ultraviolet and infrared light. The material's durability makes it suitable for creating wear-resistant coatings and advanced ceramics. Moreover, fused silica powder finds utility in glassmaking, providing a key ingredient for specialty glasses, including those used in laboratory equipment and fiber optics. Additionally, the powder can be employed in the production of refractory materials, cosmetics, and even in some pharmaceutical formulations.
Q: Is fused silica safe for humans?
A: Generally, fused silica itself is not considered harmful under normal conditions of use. However, exposure to fine particles of silica dust, whether fused or crystalline forms like quartz, can pose health risks if inhaled over prolonged periods. Inhalation of silica dust can lead to respiratory issues such as silicosis, a lung disease characterized by inflammation and scarring of the lung tissue. To mitigate these risks, it is important to handle fused silica powder in well-ventilated areas or with appropriate respiratory protection. Adhering to safety guidelines and using the material according to recommended practices can significantly reduce potential hazards.
Q: What is the formula of fused silica?
A: Fused silica has the molecular formula SiO2, indicating that each molecule consists of one silicon atom bonded to two oxygen atoms. This compound forms when silica sand or other silicon dioxide-rich materials are melted at very high temperatures, resulting in an amorphous structure without long-range order. The amorphous nature contributes to its unique properties, such as high purity and low thermal expansion, which distinguish fused silica from its crystalline counterparts.
Q: Is fused silica safe in skincare?
A: Fused silica is generally recognized as safe for use in cosmetic and skincare products when used within established concentration limits and following good manufacturing practices. It is commonly found in products as a bulking agent, abrasive, opacifying agent, and viscosity-increasing agent. Due to its inertness and compatibility with skin, fused silica does not typically cause irritation or adverse reactions. Nevertheless, manufacturers must ensure that the particle size is appropriately controlled to avoid any potential for skin abrasion or inhalation risk. As always, individual sensitivity can vary, so consumers should perform patch tests before incorporating new products into their skincare routine.
