What is Spherical quartz powder? Spherical quartz powder has the advantages of smooth surface, large specific surface area, high hardness and stable chemical properties.Spherical quartz powder, also known as spherical silica powder, refers to amorphous Shi Ying powder material whose single particle is spherical, and its main component is silica.
Characteristics of Spherical quartz powder First of all, the spherical powder has good fluidity, and it is evenly stirred with resin to form a film. The amount of resin added is small, and the filling amount of quartz powder is high, with the highest mass fraction of 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, and the smaller the thermal expansion coefficient of the plastic packaging material. The closer it is to the thermal expansion coefficient of monocrystalline silicon, the better the performance of the produced electronic components will be. Secondly, the stress of spherical powder is only 60% of that of angular powder, and the plastic packaging material made of spherical quartz powder has the lowest stress concentration and the highest strength. Finally, the spherical powder has a smooth surface, a small friction coefficient, little wear on the mold, and can prolong the service life of the mold by more than one time. Application of Spherical quartz powder Spherical quartz powder Spherical SiO2 is mainly used for high-temperature vulcanized silicone rubber, silicone defoaming agent, advanced printing ink, powder coating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, sheet material preparation, cosmetics, etc. Spherical silica powder is not only in good shape, and high chemical purity, and low content of the radioactive element, it can meet high-end integrated circuits in all kinds of technical requirements, and its application can greatly reduce the encapsulation material thermal expansion coefficient, lower the dielectric constant, reduce stress, greatly enhance rigidity and wear resistance, weather resistance, impact resistance, compressive strength, tensile, the wave resistance, flame resistance, make the products with good arc resistance insulation characteristics and resistance to ultraviolet radiation, etc., have become the indispensable key electronic packaging materials. Spherical quartz powder is mainly used in the field of electronic packaging but is also widely used in the manufacturing of electronic ink, optical fiber, high-end cosmetics, advanced precision ceramics, precision grinding of optical devices and electronic components, and used as a filler for special paints and coatings.
