Abstract:
A porous silica particle has disintegration properties. The porous silica particle has an average particle diameter of 0.5 to 50 μm, a pore volume of 0.5 to 5.0 cm3/g, a mode of a pore diameter of 2 to 50 nm, a shape factor of 0.8 to 1.0, an average compression strength of 0.1 to less than 1.0 kgf/mm2, a sodium content of 10 ppm or less, and a network structure.
