ABSTRACTThe use of A2 Q/Q melts (A - alkali metal, Q - S or Se) for the synthesis of new one-dimensional solid-state materials is found to be of general utility and is illustrated here for the synthesis of K4 Ti3 SI4. Reaction of Ti metal with a K2 S/S melt at 375°C for 50 h affords K4 Ti3 SI4. The structure possesses one-dimensional chains of seven and eightcoordinate Ti atoms with each chain isolated from all others by surrounding K atoms. There are six S-S pairs (dave - 2.069(3) Å) so that the compound is one of TiIV and may be described as K4 [Ti3 (S)2 (S2)6]. Electrical conductivity measurements indicate that this material is a semiconductor.

In this paper, the CuFeO2compound were prepared by classical solid state reaction (CSSR) and direct powder dissolved solution (DPDS) method from starting material metal oxides and metal powders. Preparation of two methods shows that, direct powder dissolved solution faster recover phases than classical solid state reaction method. The fastest method gets from starting materials Cu and Fe metal powders, the electrical conductivity, Seebeck coefficient, carrier concentration and mobility are 10.68 S/cm, 244.59 μV/K, 12.86×1016cm-3and 494.96 cm2/V.s, respectively. In addition, each CuFeO2compounds were investigated on crystal structure and electrical properties. From XRD and SEM results, all samples have a crystal structure delafossite-typeand a large grain boundary more than 15 μm by electrical conductivity corresponds to grain boundary and lattice parameter: a increases. Within this paper, from above results exhibit that preparation CuFeO2from Cu and Fe by direct powder dissolved solution method most appropriate for thermoelectric oxide materials due to high active for preparation else high lattice strain and high power factor are 0.00052 and 0.64×10-4W/mK2, respectively.

Capillary Type

The electrical conductivity of germanium(II) sulfide in the liquid state has been measured with a capillary-type cell. Both a-c. and d-c. methods were used. The conductivity of liquid GeS increases regularly with tempersature from 1.33 Ω−1 cm−1 at 664 °C to 2.52 Ω−1 cm−1 at 705 °C. The experimental facts lead to the conclusion that GeS remains a semiconductor in the liquid state with a conduction band situated at 2.5 eV above the valence band.The energy gaps of GeS, SnS, and PbS in the solid state are compared with those of the corresponding liquids. It is concluded that these sulfides, in the liquid state, have structures very similar to that of the solids. Liquid PbS has a structure somewhat similar to that of metals. In the case of SnS and GeS, heating and melting are accompanied by a gradual loosening of the double layers which constitute the crystals. Accumulated evidence indicates that the molecular character of SnS and GeS is increased on going from the solid to the liquid state.

Powder Characteristics

Nano-sized electrolyte of CeO2 doped 8YSZ with 2%mol CuO (YSZDC)powders were synthesized by solid state reaction method. Powder characteristics and electrical properties was characterized by XRD,SEM and Electrochemical workstation.The results demonstrate that the as-synthesized Y0.08Zr0.72Ce0.2O1.6 (YSZDC) and Y0.08Zr0.72Ce0.18Cu 0.02O1.6-δ(YSZDC-Cu0.02) possessed similar powder characteristics, including cubic fluorite crystalline structure.About 150 °C reduction in densification temperature of Y0.08Zr0.72Ce0.18Cu0.02O1.6-δ was obtained when compared with Y0.08Zr0.72Ce0.2O1.6.The YSZDC-Cu0.02 pellets sintered at 1300 °C and the YSZDC sintered at 1450 °C exhibited relative densities of 95.66% and 94.73%,respectively.Electrolyte matrixs were prepared for electrolyte-supported SOFCs(ES-SOFC) , the suspension of NiO-YSZ anode was sprayed on the electrolyte, after co-sintering at 1300°C,electrolyte matrixs and anode were well adhered each othert, without connecting pores and cracks observed. Moerover, well electricity performance were showed by YSZDC and YSZDC-Cu0.02 at a testing temperature of 750°C,And the electrolyte conductivity didn’t decrease obviously with dopping CuO.
