Abstract: The viscosity of melts of the system KF—K₂MoO₄—SiO₂ has been measured using the computerized torsional pendulum method. An equation describing the dependence of the viscosity in logarithm values on composition at 1270 K was calculated by multiple linear regression analysis. The sum of viscosities of pure components in logarithm values multiplied by their mole fraction was used as an “additive” behaviour. In the concept of modified Redlich—Kister’s type equation binary and ternary interactions of the particular components were found.
