【摘要】 文章以银-钯（Ag－Pd）合金＋AgCl在HCl-H2O对热液中的溶解度测定为例，叙述了用合金作为实验初始物和同时测定合金组成的方法。本实验结果与前人在相同实验条件仅用不同方法所获得的结果比较后指出：①本实验中测得的银溶解度位于Zotov和Seward的研究结果之间；②从实验中测得把的溶解度，计算或的存在形式和控制把溶解度反应式的平衡常数与Gammons一致，所有这些结果都表明，用Ag－Pd合金＋AgCl作为溶解度反应的初始物研究该合金组成的方法是可行的。该方法提出了控制体系氧逸度的新方法，为从实验上研究成矿元素在低温下的热液行为提供了可能。更多还原

【Abstract】 Described in this paper is the method of determining the composition of a metallic alloy as the starting material in terrns of the measurements of the solubility of Ag-Pd alloy+AgCl in the HClH2O hydrothermal soluffion. Comparisons of our experimental results with those obtained by previous workers under the same experimental conditions show: (1)the solubi1ity of Ag obtained in the present experiment lies between thos’e of Zotov and Seward;and (2)the existing form of Pd and the equilibrium constant of the reaction controlling the solubility of Pd,which are calculated on the basis of the solubillty of 1,d obta1ned 1l1 the experiments,a new approach has been proposed to controlling the oxygen fugacity of the 5,ysteml thus providing a possibility of experimentally investigating the hydrothermal behavior of ore-forming elements under low temperature conditions.更多还原
