Abstract

LA INVENCION SE REFIERE A LA PRODUCCION DE MICROESFERAS CUYA COMPOSICION HACE APARECER UN CONTENIDO MUY FUERTE EN SILICE. EN EL PROCEDIMIENTO SEGUN LA INVENCION, SE UTILIZA PARA MATERIAL INICIAL UN VIDRIO CUYO CONTENIDO EN SILICE ES INFERIOR A 80% EN PESO, ESTANDO EL RESTO ESENCIALMENTE CONSTITUIDO POR OXIDO DE BORO Y OXIDO(1) ALCALINO(1), ESTE VIDRIO, ES REDUCIDO A FINAS PARTICULAS POR TRITURACION, LAS PARTICULAS SE SEPARAN POR LA LLAMAS DE UN GENERADOR A UNA TEMPERATURA AL MENOS IGUAL A 1500 (GRADOS) C Y BRUSCAMENTE ENFRIADAS, LAS MICROESFERAS PRODUCIDAS SON RECUPERADAS Y PUESTAS EN CONTACTO CON UN AGENTE DE DESALCALINIZACION. EN ESTAS OPERACIONES LA DESCOMPOSICION DE LAS MICROESFERAS EVOLUCIONA SOBRE EL DIAGRAMA TERNARIO DEL PUNTO A A LOS PUNTOS B Y C.
