The influence of the powder synthesis\r process and the shrinking ratio of the sample on the structural, morphological and electrical properties of the ceramics were investigated. It has\r been found that sol–gel method is more efficient and stable to obtain ceramic samples with good electrical properties. The radial shrinking ratio of\r the ceramic increases with the decreasing calcination temperature. The experimental results show that RSR significantly affects the electrical\r properties of the ceramics prepared by coprecipitation method and has negligible influence on the samples made by sol–gel method. The\r coprecipitation samples with larger RSR have higher insulator to metal transition temperature Tp which is comparable to that of the sol–gel\r samples."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "A.
