Abstract

The invention relates to a refractory compound powder material preparation device which comprises a source metal melting unit, an atomization-reaction furnace, a cooling unit and a refractory compound powder collection and classification unit. A source metal passes through the melting unit to form a liquid stream, the liquid flow enters the atomization unit, and the molten metal is atomized to form tiny liquid drops to react with reactant gas, so that the metal liquid drops are converted into refractory compound powder; and meanwhile, the metal liquid drops continuously react under the action of a grain homogenizer to form multielement refractory compound crystal grains. The crystal grains are cooled and subjected to grain collection and classification to obtain the refractory compound powder material. The device integrates the functions of melting, atomization, reaction, synthesis, cooling, collection and classification, and can be used for preparing the refractory compound powder material with high purity and uniform grains. The device has the advantages of high efficiency and small influence on the environment, and is suitable for popularization and application in the field of powder metallurgy.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a device for preparing refractory compound powder materials. Background technique [0002] Refractory compounds, including refractory metals, alloys and their refractory compounds and composite materials, have always been developed as high-tech materials due to their unique high melting point and other unique properties, especially in national defense and military industries. Aerospace, electronic information, energy, chemical defense, metallurgy and nuclear industry and other fields play an irreplaceable role, and are highly valued by countries all over the world, and have become one of the most active research fields in the material science community. [0003] In nature, refractory refractory compound materials rarely exist, especially high-purity refractory compound materials. At present, most refractory compound materials are obtained by using additives and catalysts when pr...
