摘要: Strontium-doped lanthanum chromites, La1−xSrxCrO3, have been synthesised to investigate the effect of strontium doping on stability and physico-chemical characteristics perovskite LaCrO3. Both microscopic X-ray examinations show that materials exist as single phase structure for all compositions up 50 mole% substitution. The further characterized by infrared electron paramagnetic resonance spectra. These a good sinterability even in air at 1773 K. Electrical conductivity thse perovskites has measured function temperature. found be maximum x=0.2. observed electrical magnetic properties are consistent with activated polaron transport mechanism conduction these materials.
