摘要 |
An inorganic composition comprises (A) 60 to 99% by weight of spherical inorganic oxide particles having a mean particle diameter greater than 0.1 mu m but not greater than 1 mu m, and (B) 40 to 1% by weight of inorganic oxide fine particles having a mean particle diameter not greater than 0.1 mu m, wherein a volume of micro pores due to strongly aggregated particles having pore diameters not smaller than 0.08 mu m is not greater than 0.1 cc per gram of the inorganic composition. The inorganic composition, when mixed with a polymerizable monomer and a catalyst, provides a composite useful for dental applications which has excellent surface smoothness, can be polished in a short time, exhibits improved bending strength, compressive strength, surface hardness and wear resistance and causes little wear on an antagonistic tooth. |
