Synthesis of La1-xSrxCrO3 Prepared by GNP and Its Property Study

Abstract

Abstract: In the present work, La_1-xSr_xCrO_3-δ (0≤ x≤0.3) was synthesized by Glycine-Nitrate-Process (GNP), and characterized by XRD, TEM
and DTA/TG. Electrical conductivity, sintering behavior 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 synthesized powders was around 30nm. However, grain agglomerates were observed in the powders,
which could be removed by short time ball-milling. Single-phase bulk materials of La_1-xSr_xCrO_3-δ were sintered at 1550℃ for 4 h.
The relative density of La_0.7Sr_0.3CrO_3-δ was 91.7%. The electrical conductivity of La_0.8Sr_0.2CrO_3-δ was 14.7S·cm^-1.

Key words: GNP, interconnector, lanthanum chromites, electrical conductivity
