摘要：

Enthalpies of solution of kyanite and sillimanite in lead borate solvent (2PbO. B//2O//3) have been determined calorimetrically at 701 plus or minus 2 C; from observed values for one sample of kyanite and two different samples of sillimanite enthalpies of transformation kyanite to sillimanite were redetermined to be 1. 42 plus or minus 0. 18 kcal/g. f. w. and 1. 52 plus or minus 0. 23 kcal/g. f. w. , respectively at 701 C; from these values P-T equilibrium curves for kyanite-sillimanite equilibrium for pressures below 12 kbar are recalculated.
