Preparation of porous silicon nitride ceramics by microwave sintering and its performance evaluation

Preparation of porous silicon nitride ceramics by microwave sintering and its performance evaluation

In this paper, the preparation methods of porous silicon nitride materials with controllable dielectric constant and pore structure were systematically studied. By using microwave sintering technology, porous silicon nitride materials with high closed pore ratio were prepared by adjusting the conten...
