Abstract

The goal was to study the structure of glass ionomer cements (GIC) developed on the basis of glasses of the SiO₂-Al₂O₃-CaO-ZnO-P₂O5-CaF₂ system. Glass powders with sizes less than 50 μm were sealed with a 40% solution of polyacrylic acid and after 72 hours, electron microscopic examination was carried out on a JSM-IT200 scanning microscope (JEOL, Japan). All samples demonstrate a cellular structure consisting of glass particles surrounded by glass elements that have entered into an acid-ion interaction with polyacrylic acid in a polymer matrix. GIC-4 and GIC-6 show the most finely dispersed, and GIC-2 the least coherent.
