GRANULAR INORGANIC MOLDINGS AND A PROCESS FOR PRODUCTION THEREOF

摘要

According to the present invention, there is provided granular inorganic moldings characterized in that when the ratio A/D of the maximum diameter D and the maximum length A perpendicular to the maximum diameter of the granular molding is 0.5 to 0.9 and in that at least 80% of the granular moldings have a shape such that the crossing point of A and D is within 0.3D from both sides of the center of D. Such moldings can be obtained in a high yield by filling inorganic powders capable of calcination into an organic porous body having a 3-dimensional net-like structure and subjecting it to press forming thereby to form granules of the inorganic powders in pores of the porous body and then burning off the organic porous body and at the same time, calcining the granular molding. The granular inorganic moldings are useful as bone fillers, etc.
