Fused Silica Powder

Fused Silica Powder is a micro powder primarily made from non-crystalline silicon dioxide, which is derived from natural quartz through high-temperature melting and cooling. It undergoes unique processing techniques to transform its molecular structure from an ordered arrangement to a disordered one, resulting in a white color and high purity. Fused Silica Powder finds applications in various industries, including electronic packaging, investment casting, premium electrical insulation, paints and coatings, silicone rubber, etc. Due to its characteristics of high purity, low impurity content, low thermal expansion coefficient, and low thermal conductivity, it outperforms crystalline silica powder in terms of signal transmission speed, quality, and reliability in electronic products. It can be used in copper clad laminates for smartphones, automobiles, network communications, and industrial equipment; epoxy molding compounds for integrated circuit packaging in air conditioners, washing machines, refrigerators, charging piles, photovoltaic components, etc.; as well as in adhesives, coatings, ceramics, and encapsulants.
