Abstract

Se produce un carbonitruro de metal de transicion submicrometrico que tiene la formula MaM'bM''(1-a-b) (c(1-x)Nx)z, en donde M es Ti, Zr o Hf; M' es V, Nb o Ta; M'' es Cr, Mo o W; a varia de 0 a 1; b varia de 0a 1 con la salvedad de que (a+b) es menor que o igual a 1; x varia de 0.02 a 0.95 y z varia de 0.9 a 2. El carbonitruro de metal de transicion se produce mezclando (a) una fuente de oxido de metal de transicion de un metal de transicion de la formula anteriormente citada y (b) una fuente de carbono tal como negro de carbon. Esta mezcla se calienta a un regimen de entre 100 grados K por segundo a 100,000,000 grados K por segundo en un gas no oxidante que contiene nitrogeno tal como nitrogeno o nitrogeno mezclado con argon hasta una temperatura elevada y hace que la reduccion carbotermica de la fuente de oxido de metal de transicion sea favorable termodinamicamente para un tiempo de permanencia suficiente para convertir la fuente de oxido de metal de transicion en por lo menos un producto que se selecciona del grupo que consiste de: (i) un carbonitruro de metal de transicion y (ii) un precursor del carbonitruro de metal de transicion. El producto puede exponerse a un paso de acabado que involucra calentar el producto a una temperatura menor que la temperatura elevada en la atmosfera de acabado tal como nitrogeno, hidrogeno, gas inerte o una combinacion de los mismos a fin de formar carbonitruros submicrometricos de pureza mas elevada o estequiometria diferente.
