以ＢａＴｉＯ３和ＴｉＯ２为原料，采用传统制备工艺，混合后的粉料于不同合成温度（８００—１１５０℃）和不同保温时间（１／６０—６４ｈ）进行固相合成反应．基于对合成产物的相分析，研究了Ｂａ２Ｔｉ９Ｏ２０的合成过程．最终制备出单相的Ｂａ２Ｔｉ９Ｏ２０粉体和致密的（大于理论密度值的９８％）Ｂａ２Ｔｉ９Ｏ２０陶瓷（１２４０—１３００℃，３ｈ）．
BaTiO3 and TiO2 were used as raw materials and the traditional preparation process was used. The mixed powders were subjected to solid phase synthesis reaction at different synthesis temperature (800-1150 ℃) and different holding time (1/60-64h). Based on the phase analysis of the synthesized product, the synthesis of Ba2Ti9O20 was studied. Finally, single-phase Ba2Ti9O20 powder and dense (more than 98% of the theoretical density) Ba2Ti9O20 ceramics were prepared (1240-1300 ℃, 3h).
