Abstract Silicon nitride ceramic is a kind of high-temperature structural ceramic with excellent performance and broad development prospects. High-purity and ultra-fine silicon nitride powder is the key and foundation for preparing excellent silicon nitride ceramic. The preparation methods of silicon nitride ceramic powder were mainly introduced, the advantages and disadvantages of various preparation methods were analyzed, and the current research situation was pointed out. Finally, the prospect of the preparation of silicon nitride powder was looked forward.
