Abstract: Amorphous boric oxide-containing product having about 80 to 90% B2O3 is produced by heating boric acid to an elevated temperature of about 180 DEG to 220 DEG C. to dehydrate the boric acid and form a molten glass which is cooled to a solid glassy product. The solid glass can be comminuted to produce a particulate product. Preferably the boric acid is heated at about 195 DEG to 205 DEG C. The process is readily adapted to a continuous process in which the boric acid is continuously fed through a heated reactor-mixer such as a Kneadermaster mixer or Discotherm mixer. The molten glassy product is cooled to form a solid glassy product which can be comminuted to a desirable particle size range.

Abstract: Amorphous boric oxide-containing product having about 80 to 90 % B2O3 is produced by heating boric acid to an elevated temperature of about 180° to 220 °C to dehydrate the boric acid and form a molten glass which is cooled to a solid glassy product. The solid glass can be comminuted to produce a particulate product. Preferably the boric acid is heated at about 195° to 205 °C. The process is readily adapted to a continuous process in which the boric acid is continuously fed through a heated reactor-mixer such as a Kneadermaster mixer or Discotherm mixer. The molten glassy product is cooled to form a solid glassy product which can be comminuted to a desirable particle size range.
Abstract translation: 通过将硼酸加热至约180℃至220℃的高温以使硼酸脱水并形成熔融玻璃并将其冷却成固体玻璃状产品，从而制备具有约80至90％B 2 O 3的含无定形氧化硼的产品。 可以粉碎固体玻璃以产生颗粒状产品。 优选硼酸在约195℃至205℃下加热。 该方法容易适用于连续过程，其中将硼酸连续加入通过加热的反应器 - 混合器如Kneadermaster混合器或Discotherm混合器。 熔融的玻璃制品冷却形成固体玻璃状产品，可将其粉碎成合适的粒度范围。

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.
