HEATS OF FORMATION OF METALLIC BORIDES BY FLUORINE BOMB CALORIMETRY

Abstract

The heats of formation of AlB2 and AlB12 were calculated. Uncertainties of the heats of formation, estimated as the standard deviations of the means, are 2.1 and 1.8 kcal mole, respectively. The samples were completely analyzed and carefully characterized. Some combustion measurements on impure zirconium borides are reported. A review with 85 references is given of the available thermodynamic data on borides.
