Abstract

Procedure for the manufacture of molded bodies of boron nitride by pressing and sintering, characterized in that a mixture of 95-50% by weight of boron nitride, 5-50% by weight of aluminum phosphate, preferably aluminum monophosphate and auxiliaries of solution, for example water, at room temperature and at a pressure of 1 to 10 t/cm2 are pressed in a block, then, outside the press mold, they are dried at 200ºC and then, under a pour of BN powder, they are sintered at a temperature of 1,000 to 1,500ºC.
