EFFECT OF THERMAL CONDITIONING OF THE SODIUM SILICATE GLASS ON THE VALUE OF ZETA POTENTIAL OF THE SOLUBLE SODIUM SILICATE

Problems connected with a change of Zeta potential values of soluble sodium silicate are presented. Soluble sodium silicate was made from sodium-silicate glass to thermally conditioned at a temperature of 1350°C for 60, 90 and 120 minutes. It was found that particles in all types of the soluble sodium silicate have similar electrokinetic properties. In the soluble sodium silicate made from the sodium-silicate glass subjected to thermally conditioned for 120 minutes, particles with the highest value of the Zeta potential were present. They provide the most intense laser light scattering.
