Abstract

METODOS DE PREPARACION DE CUERPOS MOLDEADOS A PARTIR DE MATERIAL SILICATICO. COMPRENDE LA FORMULACION DE UNA MASA DE MOLDEO A BASE DE ACIDOS SILICICOS ESTRATIFICADOS EN FORMA DE POLVO, DE FORMULA GENERAL H2SYO2YB1, EN LA QUE Y VALE ENTRE 1,7 Y 24, O DE SUS SALES, EN LAS QUE EL HIDROGENO ESTA REEMPLAZADO TOTAL O PARCIALMENTE POR UNO DE VARIOS CATIONES MONO- O DIVALENTES, ASI COMO AGUA O UN DISOLVENTE ORGANICO; MOLDEO DE LA MASA ASI FORMULADA PARA FORMAR CUERPOS DE CILINDROS O DE TUBOS, SECADO EVENTUAL DE LOS CUERPOS MOLDEADOS; Y, FINALMENTE, SE ATEMPERA EN LAS CONDICIONES EN LAS QUE EL MATERIAL SE TRANSFORMA PRINCIPALMENTE EN CRISTOBALITA Y TRIDIMITA. ESTOS COMPUESTOS MOLDEADOS TIENEN APLICACIONES PARA SOPORTES DE CATALIZADORES ASI COMO PARA AISLAMIENTO TERMICO EN UN AMPLIO MARGEN DE TEMPERATURAS.
