Preparation method for silicon nitride nano-material
Belonging to preparation methods of ceramic materials, the invention relates to a preparation method for a silicon nitride nano-material. The method includes: in argon atmosphere, placing the mixture of silicon tetrachloride and lithium nitride in a special stainless steel reaction kettle and performing sealing, putting the special stainless steel reaction kettle into a resistance crucible furnace and conducting heating, subjecting the product to alcohol washing, acid pickling and water washing to neutral, and carrying out separation and drying so as to obtain the silicon nitride nano-material. The preparation method for the silicon nitride nano-material has the characteristics of simple equipment, low reaction temperature, short reaction time, environment-friendliness, simple and easily controllable operation, good shape morphological product, cheap raw materials, mild reaction conditions, simple operation, and easy realization of industrial production, provides further convenience for application in relevant fields, and has significant practical value.
