Capillary-crystallizing strength of the glass mixture

The attraction of glass particles simulating grains of quartz sand by capillary collars of aqueous solutions of sodium sulfate and sodium carbonate of various concentrations is experimentally studied. It is shown that the attraction of particles in the first moments of contact with the bridge liquid is due to capillary interaction. With the evaporation of water and saturation of the solution, additional adhesion of solid particles was found, caused by the formation of crystallization contacts. Il. 5, bibliography: 2 titles.
