Spherical silica powder is a kind of spherical granule, which main material is amorphous quartz powder. It is mainly applied in integrated circuit package, as well as aviation, chemical industry, CD-RW, large-sized electronic board, special ceramics and other high-tech field.
With the rapid development of China's electronic information industry, the productions and sales of electronic information products, such as mobile phones and personal computers have entered the forefront of the world, which enlarge our integrated circuit market. With the high performances of high dielectric, heatproof, moisture-proof, corrosion resistance, high filling content, low expansion, low stress, low impurity, low coefficient of friction, it has become an indispensable high quality materials for large or super large scale integrated circuits board and packaging materials.
Basic characteristics:
1.High sphericity : spherical granule, particle size of 2~3μm
2.Good dispersity: low surface energy, smooth shape, disperse easily
3.small specific surface area: no gap on surface, low moisture content
4.Narrow range of particle sizes: can be controlled, graded process easily
5.High purity: high purity material, special technique process, low ion impurity，Low crystallization content.
Â
Application:
1.Epoxy Molding Compound:Â
Fillings for epoxy Molding Compound, increase intensity and thermal conductivity, also save lots of resin.
2. Copper Clad Laminate: increase intensity and thermal conductivity, reduce the source error
3. Electronic ink: better coverage, bright color
4. Optical fiber: high quality fiber raw material
5. Cosmetics: due to the good dispersion and oil-water compatibility, can be used in lipstick, foundation and cream
6. Ceramic composite materials: due to the high dielectric, low thermal expansion coefficient and good electric insulation, it can be used in fine ceramic, electronic ceramic, raw material for Synthetic mullite, enamel glaze and special refractory material.
7. Paint industry: with the characteristics of ultraviolet absorption and infrared reflection, Â enlarge its service life and improve the coating quality.
