Abstract

UN PROCEDIMIENTO PARA LA CONSOLIDACION DE PIEZAS CONSTRUCTIVAS CERAMICAS. LOS CUERPOS CERAMICOS POROSOS, PREVIAMENTE CONFORMADOS, SE SUMERGEN EN UNA SUSPENSION DE UN MATERIAL QUE NO CONTIENE NINGUN AGENTE AUXILIAR DE SINTERIZACION, A CONTINUACION SE EVAPORA EL DISOLVENTE, LOS CUERPOS ASI OBTENIDOS SE SUMERGEN EN UNA SEGUNDA SUSPENSION DE UN MATERIAL SINTERIZABLE, QUE CONTIENE UNO O VARIOS AGENTES AUXILIARES DE SINTERIZACION, A CONTINUACION SE EVAPORA EL DISOLVENTE, LOS CUERPOS ASI OBTENIDOS SE SINTERIZAN A TEMPERATURA ELEVADA EN UNA ATMOSFERA DE GAS PROTECTOR DURANTE UN TIEMPO SUFICIENTE, LOS CUERPOS PROVISTOS DE UNA CAPA SINTERIZADA DENSAMENTE SE CONSOLIDAN ISOSTATICAMENTE EN CALIENTE SEGUPN PROCEDIMIENTOS EN SI CONOCIDOS, Y SE ELIMINAN MECANICAMENTE AMBAS CAPAS DE CAPSULAS.
