High Whiteness Quartz Glass Powder Description:
High Whiteness Quartz Glass Powder provided by Stanford Advanced Materials is made of high-purity silicon dioxide through grading, calcining, crushing, and grinding. High Whiteness Quartz Glass Powder has small particles, when a large amount of powder is piled up together, the light is reflected and refracted inside the powder, thus canceling each other out, so the light transmittance is greatly reduced, and the whiteness can be more than 95, which is close to the color of titanium dioxide. High Whiteness Quartz Glass Powder is mainly used in high-white filler systems, and the color of the powder does not affect the color of the paint when it is used in the paint coating. In addition, it also has a low dielectric constant, low dielectric loss, and other characteristics. Widely used in electronic and electrical filler, potting material package powder, silicone, epoxy adhesive, seam sealant, rubber and plastic products filler, paint coating filler, and so on.

High Whiteness Quartz Glass Powder Applications:
1. Optical glass manufacturing: High Whiteness Quartz Glass Powder is commonly used in the manufacturing of optical glass. Due to its high purity and excellent optical properties, optical glass with high transparency, uniform refractive index, and low dispersion can be prepared for the manufacture of optical lenses, optical windows, laser devices, and so on.
2. Ceramic materials: High Whiteness Quartz Glass Powder is also widely used in the production of ceramic products. It can be used as raw materials or additives for ceramic materials and is used to prepare ceramic products with high whiteness, high strength, and high abrasion resistance, such as ceramic tiles, porcelain, ceramic handicrafts, and so on.
3. Electronics industry: High Whiteness Quartz Glass Powder is commonly used in the electronics industry, especially in the semiconductor manufacturing process. It can be used as the substrate of semiconductor wafers, materials for photolithography masks, etc. It has good electrical insulation properties and chemical stability.
4. Chemical industry: Due to its high purity and chemical stability, High Whiteness Quartz Glass Powder can also be used in the chemical industry, such as catalyst carriers, reactor linings, etc., for processing chemical and catalytic reactions.
