Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE FABRICACION DE ARTICULOS A PARTIR DE PRODUCTO DIVIDIDO, TAL COMO POLVO, POR CONFORMACION DEL MISMO Y TRATAMIENTO TERMICO. EL PROCEDIMIENTO DE LA INVENCION CONSISTE EN AÑADIR UN POLISACARIDO OBTENIDO POR FERMENTACION BACTERIANA O FUNGICA, COMO GOMA XANTANA, AL PRODUCTO DIVIDIDO DESPUES DE CONFORMADO POR TODOS LOS PRODUCTOS CONOCIDOS Y HACER SUFRIR UN TRATAMIENTO TERMICO AL ARTICULO CONFORMADO. EL ARTICULO ASI OBTENIDO PRESENTE ESPECIALMENTE MEJORES PROPIEDADES MECANICAS Y SOBRE TODO MEJOR RESISTENCIA AL IMPACTO. LA INVENCION SE APLICA PRINCIPALMENTE EN LA INDUSTRIA DE LOS CATALIZADORES Y DE LA CERAMICA.
