Sintering of heat-resistant beryllium oxide ceramics, formed by hot casting with the use of intense ultrasound, has been studied. It was found that changes associated with the homogenization of the material and a denser packing of powders at the stage of molding, as well as with the destruction and growth of defectiveness of particles, contribute to the intensification of sintering and make it possible to reduce the sintering temperature (50 - 150 ° C) and reduce shrinkage (10 - 20% ). Tab. 1, ill. 5, bibliography: 4 titles.
