“…Figure 5 shows the calculated phase diagram of the In-O binary system calculated from the present database compared with the experimental melting temperature of In 2 O 3 [24]. Figure 6 shows the Indiumrich part of the phase diagram compared with the experiments [25][26][27], the agreement is very good.…”

“…The solubility of oxygen in liquid indium was investigated first by Fitzner and Jacob [25] in the temperature range 650-820 °C using a phase equilibration technique. Later investigations using different techniques [26,27] did not confirm these results [25]. Otsuka, Sano and Kozuka [26] determined the solubility of oxygen using coulometric titrations and later Otsuka, Kozuka and Chang [27] have used an isopi-estic equilibration technique.…”

Otsuka, Sano and Kozuka [26] determined the solubility of oxygen using coulometric titrations and later Otsuka, Kozuka and Chang [27] have used an isopi-estic equilibration technique. Both measurements are in good agreement and show lower solubility of oxygen in liquid indium than determined by Fitzner and Jacob [25].…”

The In 2 O 3 -SnO 2 -ZnO system is of special interest for applications as transparent conducting oxides and also transparent semiconductors. In the present work, a thermodynamic assessment for this system is discussed using all available experimental data on phase equilibria and thermodynamic properties. All subsystems including elemental combinations were considered in order to generate a self-consistent Gibbs energy dataset for further calculation and prediction of thermodynamic properties of the system. The modified associate species model was used for the description of the liquid phase. Particular attention was given to two significant solid solution phases: Spinel with the formula Zn (2-x) Sn (1-x) In 2x O 4 based on Zn 2 SnO 4 and Bixbyite based on In 2 O 3 and extending strongly toward the SnZnO 3 composition according to the formula In (2-2x) Sn x Zn x O 3 . In addition to the component oxides, nine quasi-binary compounds located in the In 2 O 3 -ZnO binary subsystem have also been included in the database as stoichiometric phases.

“…Importantly, the time necessary for the cell to reach a new steady cell voltage with charge informs the rate of transfer of B into the alloy, and helps estimating the diffusivity in the mass transport limiting process. The diffusion phenomena can be studied, such as extensively reported in liquid metals [85][86][87][88][89] or in molten electrolytes. [90,91] B. Voltammetry An extension of the coulombic titration method is to vary the current continuously and conduct actual electrolysis, such as found in a formation cell, where the electrolyte is actively decomposed.…”

Metallurgical Transactions-and its subsequent MMTA and MMTB-has been a home for numerous contributions related to electrochemistry as it applies to solid, but also liquid materials. Herein, a perspective is presented to highlight the utility of electrochemical methods as applied to the study of liquid metals. The review of a subset of papers shows the diversity of experimental options available to investigate the thermodynamic properties of liquid metals, as well as certain limitations. A specific set of results covering the entire range of two liquid binary systems is reviewed as an illustration of the static electrochemical potential difference method. More recent developments offered by dynamic electrochemical potential methods, using direct and alternating currents or containerless configurations, are reviewed. Advances in electrochemical studies of liquid metals bring the prospect of simultaneous thermodynamic and transport properties measurements closer to reality.

“…Figure 4 shows the oxygen solubility and diffusivity at 1100 °C in some metals which are normally considered as flux for the growth of intermetallic compounds. [18][19][20][21][22] Obviously, In, Ga, and Cu have limited solubility of oxygen which disqualifies them as the flux. Ag has a good solubility and diffusivity of oxygen.…”

Flux requirements for the growth of RFeAsO (R=rare earth) superconductors

Millimeter-sized LaFeAsO single crystals have been successfully grown out of NaAs flux starting with ͑LaAs+ 1 / 2Fe 2 O 3 ͒ : 20NaAs. The factors which allow the growth of these crystals out of NaAs but not out of many other fluxes, such as FeAs, have been investigated. X-ray powder diffraction found that NaAs synthesized for the growth of RFeAsO superconductors has monoclinic LiAs structure. Thermal analysis confirmed that NaAs melts congruently at about 600 °C. The ability to extract RFeAsO crystals from this NaAs flux suggests that NaAs has a significant oxygen solubility, possibly due to the formation of the ternary compound NaAsO 2 , and enough oxygen diffusivity to transport solute to the growth front. Oxygen solubility and diffusivity are two important factors in searching for an alternative environmentally benign flux for the growth of RFeAsO superconductors.
