Abstract

UNA MEMBRANA DE MATERIAL COMPUESTO CONTIENE UN SOPORTE INORGANICO, QUE TIENE INTERTICIOS Y PELICULAS INORGANICAS POROSAS DE PARTICULAS NO METALICAS SINTERIZADAS, SOPORTADAS POR UN SOPORTE Y QUE PUENTEAN SUS INTERSTICIOS. EL SOPORTE ES PREFERIBLEMENTE UNA MALLA METALICA NO TEJIDA, CON LAS PELICULAS PRACTICAMENTE COPLANARES CON EL SOPORTE. LAS PELICULAS SE PUEDEN FORMAR APLICANDO UNA SUSPENSION DE LAS PARTICULAS REFRACTARIAS A UNA DISOLUCION DE POLIMERO, PARA PUENTEAR LOS INTERSTICIOS DEL SOPORTE Y CALENTAR LAS PELICULAS PARA SINTERIZAR PARCIALMENTE LAS PARTICULAS. PUESTO QUE LAS PELICULAS ESTAN EN COMPRESION A TEMPERATURA AMBIENTE, CUALQUIER GRIETA QUE SE PUDIERA FORMAR POR DETERIORO DE LA MEMBRANA DE MATERIAL COMPUESTO TIENDE A NO PROPAGARSE.
