Abstract
<jats:p>This article presents the dependence of the grinding kinetics of dental glass in the SrO–Al2O3–SiO2–P2O5–F system on the content of an intensifier additive based on ethanolamine and ethylene glycol in the range of 0.05-0.2 wt%. It was found that for dry grinding of dental glass, the optimal content of this intensifier is 0.1 wt%. It is shown that under industrial conditions, with the given process parameters and the addition of 0.1 wt% of an intensifier based on ethanolamine and ethylene glycol, the optimal grinding time is 20 hours. This time ensures the optimal properties of glass ionomer cement based on it. The dependence of the active site content in glass of the SrO–Al2O3–SiO2–P2O5–F system on the content of the intensifier additive introduced during grinding in the range of 0.05-0.2 wt% is presented. Confirmation of the neutralization of surface active sites by an intensifying additive is presented. Patterns of influence of 20-day aging of glass powder with an optimal additive concentration (0.1 wt%) on the acidic properties of the surface and the content of active sites are revealed.</jats:p>
