Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN POLVO CERAMICO, ADECUADO PARA PRENSADO PARA FORMAR ARTICULOS. COMPRENDE DISPERSAR UN PRODUCTO CERAMICO EN PARTICULAS, PREFEIBLEMENTE DE TAMAÑO DE PARTICULA POR DEBAJO DE 1 3, EN AGUA EN PRESENCIA DE AMONIACO O UNA ALQUILAMINA QUE TIENE UN PUNTO DE EBULLICION INFERIOR AL DEL AGUA Y SECAR POR ASPERSION LA DISPERSION PARA DAR LOS POLVOS. EL PROCESO ES PARTICULARMENTE APLICABLE A LA ZIRCONIA Y DA ORIGEN A POLVOS FINOS Y CON FLUENCIA LIBRE QUE PUEDEN SER TRANSFORMADOS EN ARTICULOS DE DENSIDAD UNIFORME.
