The heat of fusion of seventeen alkali halides was measured by means of a copper block drop calorimeter. The salts and their heats of fusion in kcal mole/sup -1/ are as follows: LiCl, 4.76; LiBr, 4.22; LiI, 3.50; NaCl, 6.69; NaBr, 6.24; NaI, 5.64; KCI, 6.27; KBr, 6.10; KI, 5.74; RbF, 6.15; RbCl, 5.67; RbBr, 5.57; RbI, 5.27; CsF, 5.19; CsCl, 4.84; CsBr, 5.64; and CsI, 5.64. The heats of fusion are believed to be accurate to at least plus or minus 1 to 2%. Except for the Li salts and, to some slight extent, the sodium salts, the entropy of fusion is constant when the anion varies, but decreases with increasing atomic number of the cation. (auth)
