What is spherical silica powder? Spherical quartz powder is a kind of powder obtained from natural quartz powder. Its phase, crystal shape and shape change instantly, from solid to molten to solid, from crystal to amorphous, and from irregular angular particles to regular spherical particles. Spherical quartz powder is the instantaneous melting of irregular quartz powder particles under the action of surface tension. Spherical quartz powder has a smooth surface, large specific surface area, large hardness and stable chemical performance. First, the spherical powder has good fluidity and resin. The amount of resin is small, the filling amount of quartz powder is high, and the quality fraction can reach up to 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, the smaller the thermal expansion coefficient of the plastic sealing material, the closer the thermal expansion coefficient of monocrystalline silicon, the better the performance of the electronic produced components. Secondly, the stress of spherical powder is only 60% of the stress of angular powder, and the stress concentration of plastic sealing material made of spherical quartz powder is the smallest and has the highest strength. Finally, the spherical powder surface is smooth, the friction coefficient is small, and the wear of the mould is small, which can prolong the service life of the mould by more than once.
Main uses of spherical silica powder Spherical quartz powder is a kind of quartz powder with a special shape and irregular structure. Spherical quartz powder has quartz material with good insulation performance, chemical stability and other characteristics. Still, it also has good fluidity because of its spherical particles, which can improve the filling rate of quartz powder in epoxy mould plastic, and has the advantages of small wear and easy dispersion; the spherical quartz powder can improve the rigidity, resistance, impact resistance, tensile resistance, arc insulation resistance and resistance of ultraviolet radiation.
