Subsolidus phase relations in the systems Ag-Sb and Ag-Sb-S.

The phase boundaries as obtained in the Ag-Sb system are as follows: Sb-rich solvus of ε phase at 500, 450, 400 and 350, and 300°C is 18.2, 17.7, 17.75 and 17.7 weight per cent Sb respectively. Ag-rich solvus of ε' phase (dyscrasite) at 500, and 450, 400, 350, 300° C is 22.5 and 22.9 weight per cent Sb respectively. Sb-rich solvus of ε' phase at 500, 450, 400 and 350°C is 27.2 weight per cent Sb and at 300°C is 26.9 weight per cent Sb. No inversion of ε’ to ε” at about 440-449°C was observed. The homogeneity range of pyrargyrite is probably less than 1 weight per cent Sb2S3 at 400° C and in miargyrite less than 0.6 weight percent Sb2S3 at 400°C

Hold-up in packed liquid-liquid extraction columns

A generalized correlation for hold-up of dispersed phase in packed liquid extraction columns has been derived and used to correlate the data of the present investigation in 2 in. column along with the reported data in 3 in. to 12 in. columns for a wide variety of liquid systems using different sizes of Raschig rings, Berl Saddles and Lessing rings
