Solubility of fine Ca-containing glass powders in aqueous medium. Calcium-silicate glass

The study of the influence of the composition of calcium silicate glasses on the behavior of powders of different dispersion (500, 60 and 10 microns) in an aqueous medium has been carried out. The acid-base characteristics of the aqueous medium and the concentration of calcium ions in the aqueous solution after holding the glass powders have been determined. It is shown that the main parameter determining the mechanism of glass dissolution in water is their basicity modulus. Tab. 2, ill. 2, bibliography: 4 titles.
