SOME PECULIARITIES OF SOLUBILITY AND CRYSTALLIZATION OF QUARTZ IN CHLORIDE SOLUTIONS AT HYDROTHERMAL CONDITIONS

摘要

On the base of the author's own, as well as published in literature, experimental data, it is shown that the character of solubility of quartz in NaCl and KCl aqueous solutions, within 200-700 deg C interval of temperatures, changes regularly as a result of inversion of the solvent acidity-alkalinity properties. Furthermore, the complex character of dependence of the quartz crystallization rate in alkali metals aqueous solutions on the mineralizer concentraton, while the constant space factor (filling of autoclave), has been explained and confirmed experimentally.
