Abstract: A method for directly preparing high quality silicon nitride powder by a combustion synthesis method, which uses the silicon powder as a raw material and uses a reactive metal as a reducing agent. The method comprises the following steps: mixing reaction raw materials such as silicon powder and a silicon nitride diluent by proportion, and then adding a quantitative amount of metal powder to uniformly mix with the reaction raw materials, placing a mixture into a combustion synthesis reaction device, and inducing the reaction under a specific pressure to obtain the high quality silicon nitride powder. According to the process method in the present invention, the reactive metal having a stronger reducibility than the reaction raw material is used to reduce oxygen in the reaction raw material so as to generate a corresponding metal oxide. The silicon nitride powder prepared by the process method in the present invention has low oxygen content, good crystallinity, high purity, and excellent sintering performance.
