Chemical Engineering Division thermochemical studies. Annual report, July 1974--June 1975

Standard enthalpies of formation were determined for the following compounds: Cs$sub 2$U$sub 2$O$sub 7$(c), $beta$-Na$sub 2$UO$sub 4$(c), BaUO$sub 4$(c), HI(aq), CsNO$sub 3$(c), Cs$sub 2$CO$sub 3$(c), CsCl(c), RbCl(c), Cs$sub 2$CrO$sub 4$(c), and Cs$sub 2$Cr$sub 2$O$sub 7$(c).Preliminary reaction calorimetric studies of WS$sub 2$ and Li--Al alloys are described. High- temperature enthalpies and other thermodynamic properties are reported for $alpha$- and $beta$-Na$sub 2$UO$sub 4$(c), Cs$sub 2$UO$sub 4$(c), and Al$sub 2$O$sub 3$(c). (auth)
