Let's talk about the use of fused silica powder. Fused silica powder is a silica powder with high purity, high insulation, low thermal expansion coefficient, low internal stress, and excellent electrical properties, which is made from fused silica, glass, etc., through grinding, precision classification, and impurity removal. .

The high purity, low dielectric constant, low dielectric loss and low thermal expansion coefficient of fused silica are superior to crystalline silicon in terms of signal transmission speed, transmission quality and reliability of electronic products. It can be used in smart phones, automobiles, network communications and Copper clad laminates for industrial equipment, and epoxy plastics such as air conditioners, washing machines, refrigerators, charging stations, and photovoltaic modules.

It can also be used in integrated circuit packaging and adhesives, coatings, ceramics, packaging materials and other fields. Fused silica powder is also called silica gel powder or silica gel powder. The raw material of fused silica powder produced by crushing, grinding and classification is fused silica. The production process of fused silica is to pulverize siliceous raw materials into small pieces of 10-20mm, adopt heap acid leaching method to remove surface impurities, rinse with water and dry. After being melted at a high temperature of 1800 °c to 2000 °c for about 10 hours, it is cooled and broken, picked manually, dried, purified, pickled, deacidified and washed with deionized water to become the raw material of silica gel powder.

The above is a small series, to give you a brief introduction to the use of fused silica powder, you can briefly understand. The content is for your reference only, and you can contact our manufacturer if you need to know about it.
