Phase behaviours of two different series of chloride salt mixtures, viz (a) equimolecular (NaCI + KCI), MgCI,, BaCI, and (b) [NaCI + KCI], MgCI,, CaClz have been studied. The percentages of
MgCI2 in the salt mixtures were kept fixed at four different valuesviz 10,20,30 and 40in these
studies where other components vary. It has been found that the replacement of CaCI, with
BaC12 in the four component salt mixtures does not change the shape and the temperature of
the liquidus curve significantly except in the cases when the percentage of BaCI, in the mixture
is more than 50
