This research project the highly densified sintered silicon nitride ceramic and atmospheric pressure in conjunction with the preparation of hot isostatic pressing. By modification of the powder and silicon nitride powder molding pre-activation, producing a high strength molded near net shape using cold isostatic pressing the ceramic body, prepared using a high-performance process atmosphere of nitrogen and hot isostatic pressure sintering combination silicon ceramic. Having high density, high precision, excellent thermal shock resistance and high thermal conductivity, it is widely used in high temperature structural ceramics and ceramic art high shock structure.

This project studies the combination of atmospheric pressure sintering and hot isostatic pressure to prepare high-density silicon nitride ceramics. Through powder modification, the silicon nitride powder is activated and pre-treated, high-strength near-net-size ceramic blanks are prepared by cold-waiting static forming, and high-performance silicon nitride ceramics are prepared by combining atmospheric pressure sintering and hot and other static pressure. With high density, high precision, excellent thermal shock performance and high thermal conductivity, widely used in high temperature structure ceramics and high-seismic structure ceramics.

In this project, high density silicon nitride ceramics were prepared by atmosphere pressure sintering and hot isostatic pressing. The high-strength near net size ceramic body was prepared by cold isostatic pressing, and the high-performance silicon nitride ceramic was prepared by atmosphere pressure sintering and hot isostatic pressing. With the advantages of high density, high precision, excellent thermal shock resistance and high thermal conductivity, it is widely used in the field of high temperature structural ceramics and high seismic structural ceramics.<br>
