摘要：
The density d at a temperature of 25°C is measured by the hydrostatic weighing method, the Vickers microhardness HV is determined, and the fluctuation free volume fraction fg is calculated for glasses in the SrO-B2O3-SiO2 system with a constant strontium oxide content in the range from 35 to 45 mol %. It is demonstrated that the quantities HV and fg decrease and the density d increases with an increase in the SrO content.
