Research progress on refractory metal and metallic carbide/oxide powder preparation techniques

Having such excellent properties as high melting point, high temperature stability, and strong corrosion resistance, refractory metals, metallic carbides and metallic oxides. These are widely used in high-temperature and high-pressure, strong corrosion and other environments such as gas blades, electronic tubes, rocket engines, cutting tools, high temperature thermal components, and turbine nozzles. Focusing on the preparation methods of refractory metals and metallic carbides/oxides powder, including the mechanical method, reduction method, combustion method, sol-gel method, hydrothermal method, microwave method, precipitation method, pyrolysis method, explosion method and plasma method, this paper analyzed the advantages, disadvantages and status of preparation methods such as Mo, W, Ta, WC, ZrC, TiC, CeO₂, ZrO₂ and Y₂O₃, and prospected the development status of the preparation of refractory powder based on electric explosion method to provide reference for the preparation and application of refractory powders.
