Physico-chemical study of the binary system Cr₂O₃ – ZrO₂
Abstract
The first published data date back to 1930, when attempts were made to study the melting diagram of the Cr₂O₃–ZrO₂ system. Having discovered the significant volatility of chromium oxide, the authors abandoned further research. The results of the work are presented in Fig. 1, which shows that the data obtained cannot even serve as approximate. These data exhaust the published information on the Cr₂O₃–ZrO₂ system. Believing that the volatility of Cr₂O₃ in itself cannot serve as an obstacle to studying the system, since the composition of each point can be determined by chemical analysis of the fused portion of the samples, after determining the melting temperature, we decided to study the equilibrium diagram of this system, which is of not only theoretical but also significant practical interest.
