Abstract

"MéTODO PARA REALIZAR REAçõES TéRMICAS ENTRE PELO MENOS DOIS REAGENTES, E, FORNO". A presente invenção diz respeito a reações térmicas realizadas a temperaturas transientes rápidas e a um forno (1) capaz de realizar tais reações. O método e o forno podem ser adequadamente aplicados para realizar reações entre reagentes onde normalmente ocorrem perdas significativas a certas temperaturas ou faixas de temperaturas transientes. Uma aplicação prática da presente invenção diz respeito a um método carbotérmico para produzir pós de Metal Duro Refratário, tais como boretos, nitretos e carbetos, e a um forno projetado para a realização do método. De acordo com este método, pós de Metal Duro Refratário, tais como pós de boreto, podem ser produzidos bom baixa perda de reagentes, tais como C e B~ 2~O~ 3~. Isto pode ser conseguido pelo aquecimento rápido da mistura contendo os reagentes numa faixa de temperatura crítica. Para a realização desta modalidade particular, um forno de duas etapas foi aplicado, em que a temperatura em cada zona de temperatura individual (37, 38) fica respectivamente abaixo e acima das temperaturas críticas da reação. De acordo com uma modalidade da presente invenção, pós de boreto, carbeto e nitreto de alta pureza com um tamanho de grão fino podem ser produzidos de uma maneira simples e de baixo custo.
