| Abstract: | In the present work, La1-xSrxCrO3 (0 x 0.3) was synthesized by Glycine-NitrateProcess (GNP), and characterized by XRD, TEM and DTA/TG. Electrical conductivity, sinteringbehavior and phase structure of as-sintered samples were measured by DC 4-probe technique,Archimedes method and XRD. It was found that the average primary grain size of the synthesizedpowders was around 30urn. However, grain agglomerates were observed in the powders, whichcould be removed by short time ball-milling. Single-phase bulk materials of La1--xSrxCrO3- weresintered at 1550 for 4 h. The relative density of La0.7Sr0.3CrO3- was 91.7%. The electricalconductivity of La0.8Sr0.2CrO3- was 14.7S.cm--1. |
