“…Eremenko and co-workers suggest that the entropy of formation of this compound may be substantial, 107,121,123 which would mean that the Neumann-Kopp rule is inappropriate. Because of the shorter temperature extrapolation, the estimates of AH0^f or the tersilicide given by Eremenko et al in Table 10 are recommended over other estimates.…”

“…Chromium silicides also have been examined by an emf method in which an NaCl-KCl-CrCl, solid electrolyte was employed (EREMENKO, et al, 1971). The standard Gibbs free energies of formation of CrSi, and CrSi between 700~850°C were reported as AG,"(CrSi,) = -18600 -1.17T and AG,"(CrSi) = -14300 -0.562'.…”

Emf measurements are reported on cells using a thoria-yttria solid oxide electrolyte. The measured potentials from two cells, Cr, CraO, IThO,-Y,Os) Co, COO and Cr, Cr,Oa IThO,-Y203\ Mn, MnO, were used to calculate the standard Gibbs free energy of formation of Cr,Oa in the temperature range 875-1275%. The two separate series of measurements are in good agreement with critically assessed data from the literature based on gas equilibration and calorimetric results. A summary of solid oxide electrolyte studies on mineral systems is presented with special attention paid to chromium-bearing solutions or compounds. The application of this experimental technique in investigating thermodynamic properties of chromium minerals is discussed:

“…For all of these reasons, CeGe 2−x has been the subject of many structural and magnetic investigations over the past five decades. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] The RGe 2−x compounds form over a range of Ge concentrations (x ≈ 0 to 0.4). Samples with x > 0.3 crystallize in the tetragonal ThSi 2 -type structure (space group I4 1 /amd) whereas samples with higher Ge content (x < 0.3) crystallize in the orthorhombic GdSi 2 -type structure (space group Imma) shown in Fig.…”

Neutron diffraction measurements on a single crystal of CeGe1.76 reveal a complex series of magnetic transitions at low temperature. At TN ≈ 7 K, there is a transition from a paramagnetic state at higher temperature to an incommensurate magnetic structure characterized by a magnetic propagation vector (0 0 τ ) with τ ≈ 1 4 and the magnetic moment along the a axis of the orthorhombic unit cell. Below TLI ≈ 5 K, the magnetic structure locks in to a commensurate structure with τ = 1 4 and the magnetic moment remains along the a axis. Below T ⋆ ≈ 4 K, we find additional half-integer and integer indexed magnetic Bragg peaks consistent with a second commensurately ordered antiferromagnetic state.
