โœฆ Synopsis

  1. phase is synthesized by solid state method. The X-ray diffraction technique, scanning electron microscope, electrical and thermoelectric power measurements were used to characterize the prepared samples. The samples are sintered from 1123 K to 1143 K and the effect of sintering on the structural and transport properties was investigated. All the above measurements showed that in the samples, there is nearly single (2223) phase. The Seebeck coefficient measurements shows that all the samples under investigation are p-type materials with hole carriers predomination over the measured temperature range. Using the electrical resistivity and TEP data, the power factor S 2 /q was calculated and exhibits good indication to wide application of the investigated compositions as thermoelectric materials.

We present the results of an investigation into the Jc dependence on processing time for silver and a silver alloy sheathed (Pb,Bi)2223 tapes sintered at 830ยฐC. The peak Jยข for the silver alloy and silver tapes was found to differ in magnitude and sintering time (Jc,,l,oy= 14250 Acre -2, Jยข,^s=7500

A systematic investigation of lanthanum-based manganite, La 0.67 Ca 0.33 MnO 3 , has been undertaken with a view to understand the influence of varying crystallite size, in the nanoscale, on various physical properties. The materials were prepared by the sol-gel route by sintering at four different
