KCI-CsBr-CaBr2相图的研究

A computer prediction for the regularities of formation of binary bromide system was made. The results indicate that CsBr-CaBr2 molten salt system is binary complex compound-forming system. The phase diagram of CsBr-CaBr2 system has been determined by visual polythermal method in order to prove the prediction. The phase diagrams of the quasibinary system KCl-CsBr, KC1-CaBr2 and the quasiternary system CsBr-CaBr2-KC1 were determined by using visual polythermal method. The phase diagrams of CsBr-CaBr2 and KCl-CaBr2 show that the intermediate compound is formed. The results are in agreement with the computer prediction. Here, the various parts of the phase diagram of the quasiternary system CsBr-CaBr2-KCl were discussed.
