Abstract
Free surface energy values of quartz-water interface were measured in 300-600-degrees-C temperature range at 50 and MPa pressure. The measur ements were obtained by the determination of solubility of thin- and c oarsegrained fraction of quartz powder. It was found that free surface energy value decreases corresponding to water density increase with t he linear dependence of reciprocal density value. Such behavior of fre e surface energy values could be interpreted in terms of water adsorpt ion decrease with increase in temperature. Similar free surface energy behavior is assumed for all minerals having a hydrofile surface.
