Abstract

The apparatus of Archimedean double-bob method for practicing accurate was established for density measurements of slag melts. The accuracy of density measurements at room temperature to establish measurements was determined in the following ways. Firstly, the densities of water were measured at 25, 30, 35, and 40 °C. Secondly, the densities of silicone fluids with the viscosities 0.01, 0.999, 4.850, and 29.44 Pa·s were measured at 25 °C. The measured densities have good agreement with the data of water standards with a precision of 0.07% and silicone fluid standards with a precision of 0.16%. The densities of Na2O–SiO2 slag melts with 60, 70 and 80 mol % SiO2 were measured in the temperature range from 1350 to 1500 °C. The density decreases with increasing temperature and increases with increasing SiO2 contents for all compositions. The reproducibility of this work is within the error estimation of density measurements. The density results of Na2O–SiO2 melts with 60, 70 and 80 mol % at 1400 °C show that the measurements data are within 0.23 % of the density values.
