The SrTiO3 and Y-doped SrTiO3 polycrystalline sintered bodies were synthesized by the polymerized complex (PC) process and the subsequent hot pressing at 1473 K for 1 h or at 1673 K for 2 h in Ar atmosphere. The X-ray diffraction patterns of the SrTiO3 and Sr0.9Y0.1TiO3 samples synthesized by the PC process and hot pressing at 1473 K showed that these samples were mostly composed of the SrTiO3 single...
Ca3Co4O9 ceramic powders were synthesized by the polymerized complex (PC) method and consolidated by the hydrothermal hot-pressing (HHP) technique. The observation by the scanning electron microscope indicated that the powders by the PC process showed fine and flaky grains. The density of the sintered body increased with an increase of the operating temperature, pressure and time during the HHP process...
The SrTiO3 and La- and Y-doped SrTiO3 were synthesized by the polymerized complex (PC) process and the subsequent sintering. The X-ray diffraction patterns of the SrTiO3, Sr 0.9La0.1TiO3 and Sr0.9Y0.1TiO3 powder precursor synthesized by the PC process showed that the perovskite SrTiO3 structure could be obtained. After the sintering by hot pressing, it was found that the compacts mostly remained...
Ca3Co4O9 ceramics powders were synthesized by the citric acid complex (CAC) method and consolidated by the hydrothermal hot-pressing (HHP) technique. The observation by the scanning electron microscope indicated that the powders obtained by the CAC process show plate-like grains. The density and the Lotgering factor, which was estimated from the X-ray diffraction data, of the sintered body increase...
The effects of Ti, Nb and Zr doping on the thermoelectric performance of a hot-pressed β-FeSi 2 were investigated. Ti doping did not have a significant influence on the thermoelectric properties. Nb doping decreased the electrical resistivity over the entire temperature range. The thermoelectric power of the Nb-doped samples showed lower values below 800 K and higher values above this temperature...
