Equations to calculate the room temperature density of the fused SiO2-MnO-CaF2 fluxes from their chemical composition were derived. Firstly, the equation based on the additive law was examined using density factors examined in the preceding paper. For calculation, the chemical composition of the fluxes and actual density measured by an air picnometer were put into the additive equation with fCaF2 as an unknown quantity. Thus the density factor for CaF2 was determined as 2.97. Secondly, the multiple regression equation was applied. In this case, the actual density and the chemical composition were treated by a computer to obtain the regression coefficients and the constants. Consequently, the deviation range of the calculated density from the actual one was found to be ±0.05g/cm3 for the additive equation and -0.04∼+0.03g/cm3 for the multiple regression equation.
