Abstract Due to its high hardness, high wear resistance and high bending strength, Si₃N₄ ceramic is widely used in metallurgy, chemical industry, ae-rospace and automotive engines. Hot-pressed sintering and gas pressure sintering are commonly used in the preparation of dense Si₃N₄ ceramics due to the high strength bonding of Si₃N₄ which is difficult to be compacted. However, the strict preparation conditions such as high temperature pressure sintering greatly limit the basic research and the industrial application of dense Si₃N₄ ceramics in many technical fields. Therefore, the preparation of dense Si₃N₄ ceramics were obtained at lower sintering temperature using traditional air furnace to study the phase changes and microstructures of experimental crucible, Si₃N₄ powder and sintered sample under the present conditions. The results showed that the decomposition of the Si₃N₄ caused irregular SiC fiber accumulation on the crucible surface, and much more Si₃N₄ and a small amount of Si₂N₂O phase were remained in the buried Si₃N₄ powder because of the lower oxygen partial pressure. Si₂N₂O phase were also detected on the surface, but no Si₂N₂O appeared inside the sintered body. The Si₃N₄ ceramics sintered at 1 650 ℃ have the relative density over 98% with uniform microtissue and good performance.
