降低生产高纯二氧化锆的盐酸消耗途径

DECREASING THE CONSUMPTION OF HCl IN THE PRODUCTION OF HIGH-PURE ZIRCONIUM DIOXIDE.

在生产高纯二氧化锆过程中，通过使用新型反应器、胶凝除硅、重结晶提纯、直接煅烧等工艺改革，与普通方法比较，降低了盐酸单耗约３０％。利用生产过程中回收的盐酸去中和生产过程中产生的含硅废液，生产出白炭黑。

Compared to common method,the consumption of HCl in the production of high-pure zirconium dioxide can be decreased by 30% through adopting new reactor,si-removing by gelatination,recrystallization and direct calcination.
