Thermochemical Study of Indium Nitride

Zięborak-Tomaszkiewicz I.

Polish Journal of Chemistry

2006

Vol. 80, nr 1

173-179

Fluorine bomb calorimetry was applied for determination of the standard molar enthalpy of formation f m 0 H (InN, 298.15 K). The combustion reaction of InN with fluorine was following: InN(cr) + 3/2 F2(g) = InF3(s) + 1/2 N2(g). Standard molar enthalpy of formation f m 0 H (InN, 298.15 K) = -(146.5 š 4.6) kJ/mol has been calculated from the measured standard massic energy of reaction: delta cu(InN) = -(8396.1 š 7.6) J/g. Indium nitride was analysed for trace levels of metals and other elements.

The Enthappy of Formation of Cubic Boron Nitride

Tomaszkiewicz I.

Polish Journal of Chemistry

2002

Vol. 76 / nr 8

1163-1173

The massic energies of combustion in fluorine of two specimens of cubic boron nitride have been measured in a bomb calorimeter, the standard molar enthalpy of formation delta f 0 m H(c-BN, cr, 298.15 K) = -254.6š1.5 and the enthalpy of polymorphic transition delta trs m 0 H (298.15 K) = -3.5š1.5 of the process: h-BN (cr) -- c-BN (cr) have been determined. Those quantities are compared with the values determined previously.
