Abstract

PROCEDIMIENTO PARA PREPARAR OXIDOS AMORFOS DE ALUMINA Y ZIRCONIO. COMPRENDE: A) CALCINAR LAS SALES SOLUBLES DE SULFATO DE ALUMINIO Y ZIRCUONIO A 100GC Y DURANTE 2 HORAS; Y B) TRATAR EN PRESENCIA DE SULFURICO AL RESIDUO CALCINADO CON POLIELECTROLITOS CATIONICOS, PARA PRECIPITAR LOS OXIDOS DE ALUMINIO Y ZIRCONIO. LA SAL DE ALUMINIO CONTIENE AL ELEVADO A 3+ EN UNA CONCENTRACION DE 0,3 MOLES/L Y SUPONE EL 80 POR CIENTO DE LA SAL; LA SAL DE ZIRCONIO TIENE UN ZR ELEVADO A 4+ QUE SUPONE EL 38 POR CIENTO DE LA SAL Y EL POLIELECTROLITO CATIONICO TIENE UNA IONICIDAD SUPERIOR A 3,5 MEQ/G Y UN PESO MOLECULAR DE 3 MILLONES Y ESTA FORMADO POR UNIDADES DE ACRILAMIDA O VINILAMINA. SE UTILIZA EN CIRCUITOS INTEGRADOS Y EN PREPARAR HERRAMIENTAS DE CORTE.
