Abstract
LA INVENCION SE REFIERE A ARTICULOS DE CERAMICA A BASE DE ALFA-ALUMINA MICROCRISTALINA QUE CONSTAN, AL MENOS DE 60% EN PESO DE ALUMINA CASI TODA EN FORMA DE FASE ALFA CON UNA ESTRCUTURA DE GRANO UNIFORME QUE COMPRENDE CRISTALITOS DE ALFA ALUMINA CON UN TAMAÑO MEDIO MENOR DE 0,5 MICRAS Y UNA DENSIDAD MAYOR DE 90% DE LA TEORICA. LOS ARTICULOS CERAMICOS, PARTICULARMENTE UTILES COMO FIBRAS REFRACTARIAS DE ALTO MODULO, PERLAS, ESCAMAS, RECUBRIMIENTOS Y PARTICULAS ABRASIVAS SE PRODUCEN MEDIANTE UN PROCESO EXCEPCIONAL SAL-GEL EN EL QUE POLIMEROS DE HIDROXI-HIERRO SE UTILIZAN PARA NUCLEAR LA TRANSFORMACION DE ALFA ALUMINA. UNA VENTAJA INHERENTE AL PROCESO DESCUBIERTO ES LA ESTRCUTURA DE GRANO FINO RESULTANTE QUE ES ESENCIAL PARA QUE UN ARTICULO DE CERAMICA TAL COMO UNA FIBRA DE ALFA ALUMINA TENGA UNA RESISTENCIA RAZONABLE.
