摘　　要：本文采用柠檬酸盐燃烧法制备BaCeO_3及In、Y掺杂的BaCeO_3。采用X射线粉末衍射仪对材料的物相进行了表征。结果表明,未进行掺杂的BaCeO_3需经1100℃烧结才能得到纯相的BaCeO_3材料。In掺杂的BaCeO_3需经1000℃烧结才能得到结晶性良好的纯相BaCeO_3。而Y掺杂的BaCeO_3和In、Y双掺的BaCeO_3经900℃烧结就能得到纯相、高结晶度的BaCeO_3,且不生成其他杂相。因此,In、Y掺杂能有效降低BaCeO_3的合成温度。BaCeO3 and In,Y-doped BaCeO3 were prepared by using the citrate combustion.The material phase wascharacterized by using the X-ray powder diffractometer.The results show that,the pure phase BaCeO3 obtained by sintering at 1100°C.In-doped BaCeO3 sintered at 1000°C,the pure phase BaCeO3 with good crystallinity can be obtained.Y-doped BaCeO3 and In,Y-codoped BaCeO3 sintered at 900°C,the pure phase BaCeO3 with good crystallinity can be obtained.Therefore,the synthesis temperature of BaCeO3 can effectively reduced by doping of In and Y.
