Abstract

The aim of the study is to determine the strength of the developed glass ionomer cements. As a powder of glass ionomer cements, glasses obtained in the SiO2-Al2O3-CaO-ZnO-P2O5-CaF2 system were used. The synthesized glasses are ground in a planetary mill to a dimension of less than 1 μm. Polyacrylic acid was used as the liquid. The effect of the powder/liquid ratio and the glass composition on the strength has been established.
