Abstract

EN GENERAL, LA PRESENTE INVENCION ESTA DIRIGIDA A UN PROCESO A ALTA PRESION/ALTA TEMPERATURA (HP/HT) PARA FABRICAR MASAS DE COMPUESTOS CBN POLICRISTALINOS A PARTIR DE NITRURO DE BORO GRAFITICO (GBN) CON UNA CONSIDERABLE AUSENCIA DE MATERIAL ACTIVO EN TERMINOS CATALITICOS. LA PRESENTE INVENCION COMPRENDE ESPECIFICAMENTE SOMETER UNA MEZCLA DE DIFERENTES FORMAS ESTRUCTURALES DE GBN A UNA CONVERSION SIMULTANEA DE CADA UNA DE ELLAS PARA FABRICAR UNA MASA DE CBN/COMPUESTO DE CBN. LAS MEZCLAS DE NITRURO DE BORO PIROLITICO/NITRURO DE BORO HEXAGONAL (PBN/HBN) SON IDEALMENTE APTAS PARA CONVERSION EN LAS INGENIOSAS MASAS DE CBN/COMPUESTO DE CBN DE LA PRESENTE INVENCION.
