Abstract

PARA PREPARAR UNA SUSPENSION DE UN MATERIAL CERAMICO PUEDEN UTILIZARSE DISPERSIONES ACUOSAS DE AGLOMERANTES. SEGUIDAMENTE, PUEDE DARSE A LA SUSPENSION LA FORMA DE UNA PIEZA EN VERDE, MEDIANTE TECNICAS USUALES TALES COMO COLADA EN CINTA. LA SUSPENSION PUEDE SECARSE POR PULVERIZACION PARA DAR UN POLVO QUE FLUYE PERFECTAMENTE AL CUAL PUEDE DARSELE FORMA POR PRENSADO EN SECO, COMPACTACION POR LAMINACION U OTRAS TECNICAS SIMILARES. LA RESISTENCIA MECANICA A LA TRACCION DE LA PIEZA EN VERDE PUEDE AUMENTARSE SOMETIENDOLA A UN TRATAMIENTO CON ENERGIA, TAL COMO CALOR O IRRADIACION, POR EJEMPLO, DE RAYOS ULTRAVIOLETA (UV), RAYOS X Y HACES DE ELECTRONES.
