摘　　要：采用硼酸和无水明矾及硫酸钾压块、焙烧、制备硼酸铝熔块。将浸取溶液进行二次蒸发并结晶，硫酸钾回收率大于９５％ ，纯度为９９．９３％ ，表明明矾中硫酸钾能得到充分利用。Aluminium borate melting block was prepared by the combination of boric acid,anhydrous alum and potassium sulfate. Recovery of potessium sulfate has been investigated.The results are abtained that the recovery rate is above 95% and the product potassium sulfate has a purity of 99.93%.\;
