The BNT powder was calcined at 850°C for 2h. and BLT powder at 750°C for 4h. The (1- x )BNT- x BLT samples were sintered between 1050°C and 1200°C for 4h. All samples exhibit almost a pure perovskite phase with coexistence of rhombohedral and orthorhombic phases. The average ...
江苏大学硕士毕业论文 摘要 本文研究了以钛酸铋钠一钛酸钡(简称NBBT)压电陶瓷作为功能体,以聚偏 二氟乙烯(PVDF)为基体的无铅压电复合材料。 采用固相反应法和水热法制备了NBBT粉体。实验结果表明:850"C保温3 小时可以得到纯NBBT粉体,750℃和800℃时都会有少量的杂质生成。 在水热法制备NBBT粉体中,NaOH浓度...

Thanks to the slow hydrolysis of titanium isopropoxide with bismuth nitrate pentahydrate, well crystallized BNT-based powder was synthesized at 265 掳C. Nevertheless this powder exhibited secondary amorphous phases. Such secondary phases synthesis was limited and prevented by both lowering the temperature...
