AbstractIonisation and appearance potentials were obtained for diazene HN = NH (prepared by thermolysis of TOSN2H2M, M = Li, Na, K), isodiazene H2N = N (prepared by thermolysis of TOSN2H2CS and N2H4 microwave radiolysis, respectively), and other hydrides N2Hn (cf. Table I). The following energy data (kcal/mole) have been determined for diazene: heat of formation (32), enthalpy of isomerisation to isodiazene (13), NN-dissoziation energy (122), NH-dissoziation energy (81), hydrogen atom affinity (45), proton affinity (176).

Effective Heat Of Formation

ABSTRACTAn effective heat of formation (δH') is formulated, enabling δH' to be calculated as a function of the concentration of metal and silicon available for interaction to form a silicide. A rule for first phase formation is proposed according to which, “The first silicide compound to form during metal-silicon interaction is the congruent phase with the most negative effective heat of formation at the concentration of the lowest eutectic temperature of the binary system.” The effective heat of formation concept is also extended to predict subsequent phase sequence.
