Abstract
Un producto que contiene oxido borico amorfo que tiene de aproximadamente 80 a 90 % de B203 se produce mediante el calentamiento de ácido borico a una temperatura elevada de aproximadamente 180 degree a 220 degree C pata deshidratar el ácido borico y formar un vidrio derretido que se enfría para formar un producto vidrioso solido. El vidrio solido puede triturarse para producir un producto en partículas. De preferencia, el ácido borico se calienta a una temperatura de aproximadamente 195 degree C. El proceso se adapta fácilmente a un proceso continuo en al cual el ácido borico se alimenta continuamente a través de un reactor-mezclador calentando como por ejemplo un mezclador Kneadermaster o bien un mezclador Discotherm. El producto vidrioso en fusion se enfría para formar un producto vidrioso solido que puede triturarse hasta un rango deseable de tamaños de partículas.
