The influence of precursor conditions on the phase formation, microstructure and J(c) property of Bi2223/Ag tapes were explored with XRD, DTA, SEM-EDS and transport current measurements. The results showed that the Pb content of 0.20 in the nominal composition of Bi1.8PbvSr2.0Ca3.0Cu3.0Oz is too low to lead to a fully formation of Bi-2223 phase in tapes compared with Pb content of 0.25 and 0.30. In addition, despite the Pb variations, the powders calcined at 820 degreesC resulted in the highest J(c) in final tapes against the powders calcined at 810 and 830 degreesC.

The average grain size increases with increasing calcination temperature. The zero-field-cooled (ZFC) and field-cooled (FC) magnetization curves indicate that LaMnO(3+delta) compounds obtained at 700 and 800 degrees C are ferromagnetic, while both ferromagnetic and antiferromagned c components are present in those calcined at 900 and 1000 degrees C. This is because the concentration of Mn(4+) ions drops with increasing calcination temperature. The temperature dependence of the resistivity of LaMnO(3+delta) Compounds exhibits an insulator-metal transition at about 90 K and also a low-temperature upturn with a resistivity minimum at about 40 K. Upon increasing particle size, the zero-field resistivity of the LaMnO(3+delta) powders increases due to suppression of the conduction by the insulating antiferromagnetic component. The negative magnetoresistance of a sample pellet prepared at 700 degrees C ranges from - 82% to - 88% in the temperature range of 40-100 K due to suppression of the spin-dependent scattering by an applied field.

Thermal decomposition at single temperature of 500 degrees C for each layer (conventional method) was adopted as the standard procedure. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and electrochemical impedance spectroscopy (EIS) show the standard procedure leads to compact oxide coatings, with large grain distributing on coatings and high resistance of obtained electrodes. Both applying the lower temperatures in first three under-layers (step-method) and the programming heating in each layer can, to some extent, overcome the disadvantages of the conventional procedure, and thereby improve the electrochemical activities of electrodes. By using the modified procedures, the electrode resistance is found to decrease due to the inhibition of substrate oxidation. When using the controlled programming calcination (heating rate), the coating becomes more porous and rugged.","authors":[],"categoryName":"|","doi":"","fpage":"1010","id":"d5256d82-4ec7-4046-aac0-2a6e0491761d","issue":"8","journal":{"abbrevTitle":"APS","id":"917def08-6dcf-48e9-9603-bf5509ffd610","issnPpub":"1000-6818","publisherId":"APS","title":"Acta Physico-Chimica Sinica"},"keywords":[{"id":"3e94f062-486b-4af4-95c5-64397af16e5e","keyword":"Ti/IrO2 electrode;thermal decomposition;calcination procedure;electrocatalytic activities;oxygen evolution reaction;surface characterization;organic;destruction;oxide electrodes;anodes;mechanism;temperature;kinetics;dsa(r);metal","originalKeyword":"Ti/IrO2 electrode;thermal decomposition;calcination procedure;electrocatalytic activities;oxygen evolution reaction;surface characterization;organic;destruction;oxide electrodes;anodes;mechanism;temperature;kinetics;dsa(r);metal"}],"language":"en","publisherId":"1000-6818_2006_8_1","title":"Effect of calcination procedure on the electrocatalytic activities of Ti/IrO2 electrodes in acidic aqueous solution","volume":"22","year":"2006"},{"abstractinfo":"A pure Cu (99.995 wt%) has been subjected to dynamic plastic deformation at cryogenic temperature to a strain of 2.1.
