Abstract

EN EL PROCESO DE PRODUCCION DE UNA CERAMICA DE NITRURO DE SILICIO HOMOGENEA Y DE ESTRUCTURA CRISTALINA MUY FINA, SE MUELE POLVO CERAMICO, SE MEZCLA CON PRODUCTOS AUXILIARES PARA LA CONFORMACION, SE HACEN MOLDES CON LA MEZCLA Y A CONTINUACION SE SINTERIZAN ESTOS MOLDES EN UNA ATMOSFERA DE NITROGENO. LA SINTERIZACION TIENE LUGAR, SEGUN DESCRIBE LA INVENCION, EN UN PROCESO DE VARIOS PASOS A TEMPERATURAS TMAX EN EL RANGO DE ENTRE 1700 Y 1900 UN PRIMER PASO DE TEMPERATURA SE MANTIENE UNA TEMPERATURA ENTRE 0,9 Y 0,96*TMAX DURANTE UN TIEMPO DETERMINADO DE ENTRE 10 Y 50 MINUTOS BAJO UNA PRESION DE N2 DE ENTRE 0,2 Y 1,2 MPA, MIENTRAS QUE EN UN SEGUNDO PASO DE TEMPERATURA, SE MANTIENE ESTA ENTRE 0,97 Y 0,985*TMAX DURANTE UN TIEMPO DE ENTRE 20 Y 80 MINUTOS A UNA PRESION DE NITROGENO DE ENTRE 3 Y 6 MPA. DESPUES TIENE LUGAR LA ELEVACION DE TEMPERATURA HASTA TMAX Y LA ELEVACION DE PRESION ENTRE 7 Y 50 MPA.
