Precipitated silica, also called silicate hydrate, silica, chemical formula of the general mSiO2 written in H2O, the appearance of white amorphous powder highly dispersed, are processed into granules as a commodity. The specific gravity is 2.319 ~ 2.653 and the melting point is 1750. Does not dissolve in water , in the air to absorb moisture will become the aggregation of fine particles.For other chemicals stable, resistant to high temperature does not break down, do not burn. Has a high electrical insulation, porosity, large surface area, water absorption, non-toxic.
