摘要： 在进行青藏高原某硼酸盐盐湖卤水的天然蒸发实验中确定,该卤水的蒸发析盐顺序不是按平衡溶解度相图,而是按“太阳相图”预示的亚稳过程进行。从天然蒸发过程中盐卤的浓缩倍数与浓缩卤水中硼富集倍数的一致性认为,盐卤在天然蒸发浓缩析盐过程中硼酸盐并不以固体盐形式析出,而是被赋存于浓缩卤水中。

Abstract: In this paper, we have studied behavior of borate during solar evaporation of brine. The solar evaporation of the borate-containing brine indicates that the crystallization of salts does not accord with Van'thoff's stable equilibrium diagram, but agrees with Kurnakov's solar evaporation diagram.The number of concentrated times of brine (W0brine/Wbrine) equals to that of boron enrichment (Cboron/C0boron) in concentrated brine during solar evaporation. It may be considered that the borate does not generally crystallize out till the stage of bischofite, and accumulates fully in the concentrated brine.
