Abstract

ELABORACION DE PARTES MOLDEADAS SINTERIZADAS MEDIANTE CONFORMACION DE UNA MEZCLA A BASE DE UN POLVO CERAMICO SINTERIZABLE O METALICO Y METILENOS POLIOXI O DE UN COPOLIMERIZADO CONTENDIENDO PROPORCIONES PREDOMINANTES DE UNIDADES OXIMETILENO COMO AGLOMERANTES PARA OBTENER UNA DISPOSICION COMPACTA VERDE, ELIMINANDO EL AGLOMERANTE MEDIANTE TRATAMIENTO CON ACIDOS GASEOSOS Y SINTERIZADO. PARA ELIMINAR EL AGLOMERANTE SE UTILIZA UN ACIDO QUE ES SOLIDO A TEMPERATURA AMBIENTE Y QUE SE SUBLIMA O SE FUNDE Y EVAPORA A ALTAS TEMPERATURAS.
