“…Again, first-principle calculations have shown that doubly charged vacancies in PbS exhibit the lowest formation energies in the system [20] [26] [27]. In addition, the doubly charged vacancies have been used previously in other models with success [28] and therefore will be used for modeling the defects in PbS.…”

Five-sublattice and two-sublattice models have been built to describe the PbX (X=S,Te) semiconductors using the CALPHAD method. The five-sublattice model has three additional sublattices to explicitly model interstitials, electrons, and holes. The experimental literature has been critically reviewed and many high temperature carrier concentration results used in previous assessments have been shown to be unreliable. First-principle calculations for the formation energies of neutral defects and their respective ionization energies have also been incorporated into the models. The models show an improvement over previous assessments of PbTe and are the first time PbS has not been treated as a stoichiometric compound in a CALPHAD assessment.

“…[15,16] Because different authors describe a phase in different ways and use different interaction parameters and different free energies of formation for the so-called associated species, a standard expression of this model has not been obtained. The selection of an associated species is somewhat arbitrary, and no claim is made that such a species has physical existence.…”

The thermodynamics of MnO-containing slags was reviewed, and the properties of such slags were correlated by application of the cell model. This model, together with a previously developed unified interaction parameter model for the metal phase, was used to simulate the gas-slag-metal conditions in the hearth of a ferromanganese submerged arc furnace. The calculated slag and metal compositions and distribution of Mn, Si, and K between slag, metal, and fume were compared with plant data and satisfactory agreement was obtained. A steady recirculation of potassium inside the furnace was also predicted. For a potassium percentage in the raw materials of 0.63 pct, the amount of the recirculating potassium was about 160 kg per metric ton of ferromanganese. Due to the recirculation, the average potassium content in the solid mix coming down to the hearth could be as high as 7 pct.

“…FeS-PbS system was studied by many authors [5,6,[8][9][10][11][12] and its state diagram was plotted. State diagram of the system is quasibinary, of an eutectic type, but in state diagrams the system differs for the composition and temperature of eutectics, as well as absence or presence of FeS phase transitions.…”

According to the results of differential thermal, X-ray phase and microstructural analyses the character of interaction in Fe-Ga 2 S 3 -PbS quasi-ternary system was studied and triangulated. It was determined that FeS-Ga 2 S 3 -PbS quasi-ternary system triangulates with eutectic type FeS-PbGa 2 S 4 , FeS-Pb 2 Ga 2 S 5 and FeGa 2 S 4 -PbGa 2 S 4 quasi-binary sections to pseudo-ternary systems. In this systems a new quasiternary phase has not been found.
