The ternary system BaO-ZnO-SiO₂

Abstract

The equilibrium relationships in the greater part of the ternary system BaO-ZnO-SiO₂ have been determined. Fifteen ternary invariant points have been located; six of these are eutectics, and the minimum melting point in the system is 1100º at a composition of 41.7% BaO, 17.00/0 ZnO, 41.3% SiO₂ by weight. Five ternary compounds with molar ratios of BaO : ZnO : SiO₂ of 1 : 1 : 1, 1 : 1 : 3, 1 : 2 : 2, 2 : 1 : 2, and 2 : 3 : 3 are described.
