Abstract: The solubility of quartz in the aqueous solutions of 1, 3 and 7% sodium chloride concentration was measured at the temperatures up to 500℃ and at the packing ratios from 1/3 to 1/1.6ml/ml by observing the loss in the weight of quartz blocks in contact with the solution. The solubility of quartz in sodium chloride solution was larger than in water at temperatures above 280℃, and rose more rapidly with temperature than in water. Reproducible values were not always obtained at temperatures above 340℃ to the critical temperature in the same conditions, and the solubility values were roughly classified into three groups, higher, lower and intermediate. The results under supercritical conditions being considered as the effect of sodium chloride on the solubility of quartz in steam, it is shown that the smaller the density of steam is, the larger the effect of sodium chloride, and the effect can not be found when the density is sufficiently large. As the results the author gave some consideration on the effect. of sodium chloride on the equilibrium in the quartz-water system.
