Preparation of porous silicon nitride ceramics by freeze drying
Silicon nitride ceramics have excellent mechanical properties, good thermal and chemical stability, low dielectric constant and dielectric loss. It is an ideal choice for high-speed aircraft electromagnetic wave transmission materials. In this paper, the preparation methods of porous silicon nitride...
