The influence of the technological parameters of glass melting of the selected composition in the SrO–Al2O3–P2O5–SiO2–F system on the value of the refractive index and the amount of fluorine that remains in the glass structure after melting is investigated. The use of a joint lowering of the melting temperature and tableting of the charge leads to an increased absorption of fluorine in the glass up to 17 wt. % at the same time, the value of the refractive index decreases to nD = 1.49. It has been experimentally established that in the selected multicomponent glass for glass ionomer cements with two glass-forming oxides SiO2 and P2O5 with a high content of Al2O3, each mass percentage of fluorine reduces the refractive index ?3.5•10–4 units.
