| 摘 要： | 硝酸盐钾盐沉积，在世界上一些极度干旱的沙漠地区有报道，新疆吐鲁番和大洼地的盐类沉积物中发现硝酸盐钾盐组合。本文从含硝酸盐水盐体系相平衡的角度，分析硝酸盐钾盐沉积的物理化学依据，推断水硝碱镁矾相同在Ｋ＾＋，Ｎａ＾＋，Ｍｇ＾＋／Ｃｌ＾－，ＮＯ＾－３，ＳＯ＾２－４－Ｈ２Ｏ六元体系干基图中的位置，并用实验进行了验证。

| Abstract: | Nitrate-potash salt deposits mainly occur in extremely dry desert regions of the world. In China, the nitrate-potash salt assemblage has been discovered in salt deposits in Turfan and Dawadi of Xinjiang. This paper reports an experimental survey on the physical-chemical relations of the nitrate-potash salt assemblage. On the basis of sufficient experimental data, the equilibrium stability area of humberstonite has been well established and constrained, which has been shown in a set of phase diagrams in the K+ , Na+ , Mg2+/Cl- , NO3- , SO42--H2O system. |
