| titleOfInvention | Method for preparing metal nitrides |
| abstract | FIELD: inorganic chemistry, chemical technology, chemical industry. n SUBSTANCE: method involves preparing a mixture containing metal oxide for nitriding, metal powder for nitriding and alkaline metal azide. As nitriding metal Nb, Ti, Zr and Hf can be used, and sodium azide can be used as alkaline metal azide. Samples are molded from the prepared mixture and placed into reactor, subjected to vacuum effect, washed out with nitrogen, filled with nitrogen to required pressure and ignited by tungsten spiral. Product obtained after combustion is decomposed and metal nitride powder is prepared. The yield of metal nitride is 96%, not less, with nitrogen content 7.17%, not less. Residual nitrogen is absent. Invention can be used in making heat-resistant, resistant to wear, resistant to erosion and chemically resistant articles. n EFFECT: improved method for preparing. n 7 ex |
