Abstract

UN PROCESO PARA PREPARAR UN MATERIAL DE NITRURO DE SILICIO DE FASE ALFA Y POSTERIORMENTE CONVERTIRLO EN UN MATERIAL DE NITRURO DE SILICIO DE FASE BETA NO DENSIFICADO INCLUYE LA PULVERIZACION DE UNA SUSPENSION ACUOSA ESPESA QUE INCLUYE UNA MEZCLA DE MATERIAL PULVERIZADO DE SILICIO Y AGUA PARA FORMAR SUPERFICIES NUEVAS NO OXIDADAS EN EL MATERIAL PULVERIZADO DE SILICIO Y PARA PERMITIR LA REACCION QUIMICA SUBSTANCIAL ENTRE EL SILICIO Y EL AGUA, LA REDUCCION DEL CONTENIDO DE AGUA DE LA SUSPENSION ACUOSA ESPESA QUE HA REACCIONADO A UN GRADO SUFICIENTE PARA FORMAR UNA MASA DESHIDRATADA RESULTANTE, LA NITRURACION DE LA MASA DESHIDRATADA POR EXPOSICION A UNA CANTIDAD SUFICIENTE DE GAS DE NITRURACION QUE INCLUYE, AL MENOS, NITROGENO A UNA TEMPERATURA SUFICIENTE DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA FORMAR UNA MASA DE NITRURO DE SILICIO DE FASE ALFA SUBSTANCIALMENTE Y LA CONVERSION DE LA MASA DE NITRURO DE SILICIO RESULTANTE A UNA TEMPERATURA DE CONVERSION COMPRENDIDA ENTRE 1450 (GRADOS) C Y 2100 (GRADOS) C, APROXIMADAMENTE, DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA CONVERTIR EL NITRURO DE SILICIO A PARTIR DE UN MATERIAL DE FASE ALFA EN UN MATERIAL DE NITRURO DE SILICIO DE FASE BETA PREDOMINANTEMENTE NO DENSIFICADO.
