Abstract: Nano structured LaCaxCr1-xO3- have been synthesized by a novel sol-gel method, in different mole ratios with x=0, 0.2, 0.4, 0.6, 0.8 and 1.0 and characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM) EDX and FTIR were employed to study the structural phases. The compounds were sintered at 700C for 6 hrs and were subjected to DC resistance measurements at RH 5-98 % and temperature dependent studies. The change in surface conductivity as a function of applied field was measured using picoammeter (Keithely-6485). Response and recovery times were measured.
