Abstract

PROCEDIMIENTO PARA LA FABRICACION DE UNA CERAMICA DENSA DE CARBURO DE SILICIO. SE UTILIZA COMO MATERIA PRIMA UN POLVO DE CARBURO DE SILICIO EN FASE ALFA, AL QUE SE LE AÑADE BORO DISPERSADO EN UN LIQUIDO ORGANICO VOLATIL, Y SE TRITURA EN UN MOLINO DE BOLAS. SE TRATA CON ACIDO CLORHIDRICO Y SE LAVA CON AGUA PARA A CONTINUACION SOMETERSE A UN TRATAMIENTO TERMICO A 1.200 GC. SE LE AÑADE AL POLVO UN PRODUCTO CARBONADO, COMO LACA FENOLITICA, Y SE AMASA EN UN MOLINO DE BOLAS REVESTIDAS DE POLIETRAFLUORETILENO. SE SECA Y SE TAMIZA PARA A CONTINUACION FRITARSE LA MEZCLA A UNA TEMPERATURA DE 2.100 GC. SE UTILIZA PARA LA FABRICACION DE COMPONENTES DE TURBINAS DE GAS Y DE MOTORES DIESEL. E
