Water wetting films on a quartz surface were found to become unstable with increasing temperature. This is believed to be associated with the temperature dependence of the structure of the water in the layer at the wall. Aparameter characterizing the strength of the structural forces is calculated from measurements of the contact angle. The sign inversion of the parameter is associated with the forces of hydrophobic attraction predominating over the forces of hydrophilic repulsion in a definite temperature interval. The results of deferrization of glass quartz sands by flotation during thermal action on water wetting films are presented.

Key words
