Abstract

UN PRODUCTO QUE CONTIENE OXIDO BORICO AMORFO CON APROXIMADAMENTE UN 80 A 90 % DE B SUB,2}O SUB,3} ES PRODUCIDO CALENTANDO ACIDO BORICO A UNA TEMPERATURA ELEVADA DE APROXIMADAMENTE 180 (GRADOS) A 220 (GRADOS) C PARA DESHIDRATAR EL ACIDO BORICO Y FORMAR UN VIDRIO FUNDIDO QUE SE ENFRIA OBTENIENDOSE UN PRODUCTO VITREO SOLIDO. EL VIDRIO SOLIDO PUEDE SER DIVIDIDO PARA PRODUCIR UN PRODUCTO PARTICULADO. PREFERENTEMENTE SE CALIENTA EL ACIDO BORICO A UNOS 195 (GRADOS) A 205 (GRADOS) C. EL PROCESO ES FACILMENTE ADAPTABLE A UN PROCESO EN CONTINUO EN EL QUE EL ACIDO BORICO ES CONTINUAMENTE ALIMENTADO A TRAVES DE UN REACTOR-MEZCLADOR CALENTADO TAL COMO EL MEZCLADOR KNEADMASTER O EL MEZCLADOR DISCOTHERM. EL VIDRIO FUNDIDO PRODUCIDO ES ENFRIADO PARA FORMAR UN PRODUCTO VITREO SOLIDO QUE PUEDE SER DIVIDIDO AL RANGO DE TAMAÑO DE PARTICULA DESEADO.
