High Purity 99.99% Spherical Silica

Our company manufactures high-purity spherical silica micro-powder using high-purity silica as raw material, processed through a flame-jet melting and spheroidizing high-efficiency process. This product features high strength, high hardness, and inert spherical particles. Its main component SiO2 content reaches up to 99.99%, with a whiteness of 95-98%, density of 2.2, Mohs hardness of 6.0, and fineness ranging from 2μ to 20μm, offering a reasonably controllable and adjustable particle size range.

It has the advantages of excellent dielectric properties, low thermal expansion coefficient, high filling amount, high fluidity, low oil absorption rate, easy dispersion and low mixing viscosity.
