Notes:
The sintering and electronic conducting properties of La0.8Ca0.2CrO3 synthesized by aglycine-nitrate process (GNP) were investigated in comparison with that synthesized by theconventional solid state reaction (SSR) method. The results demonstrate the advantage of the GNPmethod in producing La0.8Ca0.2CrO3 ceramic. Compared with the powder synthesized by the SSRmethod, that synthesized by the GNP method shows a higher sinterability due to its finemorphology. The relative densities of the ceramics made by the GNP and SSR methods attain 96.5% and 96.0 % when sintering at 1450˚C and 1550˚C, respectively. In the case of similar relativedensities, the ceramic made by the GNP method (sintered at 1450˚C) exhibits superior electronicconducting properties to that made by the SSR method (sintered at 1550˚C). This is attributed to adesired microstructure of the ceramic made by the GNP method
