Preparation method of zirconium boride-silicon carbide complex phase high temperature resistance powder material

The invention relates to a preparation method of a zirconium boride-silicon carbide complex phase high temperature resistance powder material, which belongs to the high temperature resistance powder material preparation technical field. According to the invention, zircon, zircon sand or zirconium silicate is taken as a main raw material, boron carbide, borax or boron sludge is taken as a boron source, carbon black, coke or active carbon is taken as a reducing agent, lanthana, iron oxide or alkaline earth oxide is taken as an additive, the materials are mixed according to a certain proportion, and subjected to processes of ball milling, drying, moulding, boron hot reduction/carbon hot reduction and the like to prepare the zirconium boride-silicon carbide complex phase high temperature resistance powder material. The preparation method of the zirconium boride-silicon carbide complex phase high temperature resistance powder material has the advantages of short process flow, no pollution, low cost and the like.
