摘　　要：测定了25, 100oC下H3BO3NaClMgCl2H2O体系的溶解度数据,并依据绘制的相图对我国西藏含钠镁的硼矿资源采用盐酸分解法制备硼酸的生产工艺进行了讨论.The solubility of the three component system H3BO3NaClMgCl2H2O at 25 and 100oC has been measured. On the basis of the phase diagram constructed, the process technology of producing H3BO3 by hydrochloric acid decomposition from certain Ulexite in Tibet has been analyzed.
