项目简介:
The invention relates to the field of powder metallurgy and relates to a method for producing powders of refractory compounds based on titanium carbide or nitride compounds that can be used for the production of cutting tools, metal reinforcement, and the like. In the process for the production of titanium carbide, titanium oxycarbide, titanium nitride, titanium oxynitride or titanium oxycarbonitride, which comprises the preparation of titanium oxide particle particles with amorphous carbon adsorbed on their surface and subsequent carbothermic reduction, acetylene black is added to the aqueous sulfuric titanium solution at a ratio Ti+4: Sessage not less than 1:0,5, then with continuous active stirring add at a rate of 1…2 cm3/min aqueous ammonia solution, stand up the formed pulp for 10…20 minute , Decanted, the precipitate was filtered, washed with water and dried at a temperature of 200…220 °C. The method makes it possible to obtain ultrafine powders of refractory titanium compounds by a technically simple and safe method with the possibility of strict control over the amount of carbon.
