ChemInform Abstract: Y-Fe-Al Ternary System: Partial Isothermal Section at 1070 K. Powder X-Ray Diffraction and Moessbauer Spectroscopy Study.

The isothermal section of the Fe-Zn-Nb ternary system at 600 oC was determined using the equilibrated alloys with the aid of diffusion couple approach. The specimens were investigated by means of SEM-EDS analysis, SEM-WDS analysis and X-ray diffraction. A true ternary phase T was identified, this phase is in equilibrium with ε, NbZn3, Γ, δ, and η - Zn phases respectively in the system. The solubility of Nb in η - Zn and δ phase is limited and that of Zn in ε is up to 10.0%.

The interaction of the components in the Ho-Cu-Sn ternary system was investigated at 670 K over the whole concentration range using X-ray diffraction and EPM analyses. Four ternary compounds were formed in the Ho–Cu–Sn system at 670 K: HoCuSn (LiGaGe type, space group P63mc), Ho3Cu4Sn4 (Gd3Cu4Ge4-type, space group Immm), HoCu5Sn (CeCu5Au-type, space group Pnma), and Ho1.9Cu9.2Sn2.8 (Dy1.9Cu9.2Sn2.8-type, space group P63/mmc). The formation of the interstitial solid solution based on HoSn2 (ZrSi2-type) binary compound up to 5 at. % Cu was found.

The Relationship

The relationship between composition, electrical properties, and the chemical reaction during firing of amorphous RuO2-Ag-Glass ternary system are investigated. The results are as follows.1) Iso-resistivity, iso-TCR and iso-noise index curves of the system are determined. They have a common feature with regard to their bending in the composition region containing less than about 10wt% Ag.2) X-ray diffraction and thermal differential analysis reveals the solution of Ag into glass phase in addition to the crystallization of amorphous RuO2.3) The triaxial diagram of isothermal section at 850℃ is given.4) Electrical isograms in the system are discussed in relation to the solubility of Ag into glass phase.

Plasma Technique

In this work, the partial isothermal section of the Al-Ca-Zn system in the region between 33.3 and 100 at.% Ca has been investigated at 350°C using key alloys. The actual composition of the alloys is measured by inductively coupled plasma technique. Phase relations and solubility limits of the binary and ternary compounds have been determined by means of electron probe microanalysis and X-ray diffraction. In the current work, a new ternary compound has been identified in this region with the Al9Ca31Zn10 (IM1) composition. Binary compound Al14Ca13 (IM2) has an extended solid solubility into the ternary system. The homogeneity ranges of the Al2Ca, the MgNi2-type C36 phase Al2-xCaZnx (0.28≤x≤0.70) (IM3) at 350°C and CaZn2 compounds in the pseudobinary Al2Ca-CaZn2 section have been determined at 350°C and the results are combined with the literature to construct the partial vertical Al2Ca-CaZn2 section and partial isothermal Al-Ca-Zn section at 350°C.

Impedance Spectroscopy Study

A ceramics sample of LiTaO3 was prepared using a sol-gel method. The sample is annealed at 750 °C for 48 hours. X-ray diffraction analysis indicate the formation of single phase, rhombohedral structure. An ac impedance study was used to analyse the conductivity of LiTaO3 at room temperature and at various temperatures.
