Study on the Sintering Mechanism of Tin Oxide Ceramics Doping with Pr2O3

摘要：

　　The Pr2O3 doped SnO2 dense ceramic was prepared by co-precipitation method and further sintering.Through the micrograph of the cross-sectional microstructure of the electrodes,the sintering process was analyzed and discussed.Results showed that the solid phase sintering was exhibited at the early stage;when sintering was kept going on,the instant liquid phase could be emerged due to the rich dopants in the grain boundary.Finally,there would be much secondary phase existe as the concentration of dopants reached to a certain value.
