Why does silica spheroidize?

The surface of the ball has good fluidity and can be uniformly mixed with the resin to form a film. The amount of resin added is small and the fluidity is the best. The filling amount of the powder can reach the maximum, and the weight ratio can reach 90.5%. Therefore, spheroidization means that as the filling rate of silicon powder increases, the higher the filling rate of silicon micropowder, the smaller the thermal expansion coefficient, the lower the thermal conductivity, and the closer the thermal expansion coefficient of single crystal silicon is, the more effective the electronic components produced therefrom. The better the performance. Secondly, the spherical plastic molding compound has the least stress concentration and the highest strength. When the stress concentration of the corner powder molding compound is 1, the stress of the spherical powder is only 0.6. Therefore, when the spherical powder molding compound encapsulates integrated circuit chips, the yield rate is high, and mechanical damage is not easy to occur during transportation, installation and use. The friction coefficient is small, the mold wears less, and the mold has a long service life. Compared with corner powder, the service life of the mold can be doubled. Plastic composite packaging molds are expensive. Compared with the corner powder, the service life of the mold can be doubled. Packaging molds for plastic composites are expensive. Compared with the corner powder, the service life of the mold can be doubled. Packaging molds for plastic composites are expensive.
The price of spherical silica powder varies randomly with production costs, transportation costs, international conditions, exchange rates, and market supply and demand of spherical silica powder.

Is spherical silica fume toxic?
Spherical silicon powder is a non-toxic, odorless, and non-polluting inorganic non-metallic material. It is made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after high temperature melting and cooling, cooled and crushed by natural quartz) It is made by ball milling into pulverization (or vibration, jet pulverization), flotation, pickling purification, high-purity water treatment and other processes. In short, ultrafine pulverization and purification are two important steps in the preparation of silicon micropowder. Natural quartz minerals contain a large number of inclusions. The use of ultra-fine pulverization technology can greatly reduce the number of cracks and defects.
