First, the barium titanate (BT)/BT nano-structured ceramics, whichBT nanoparticles (size: 300 nm) were strongly connected at 3-dimention, were prepared witha relative density of 60 %, and their dielectric constant was 800 while the piezoelectricconstant was 100 pm/V . Then, the potassium niobate (KN)/BT/BT nano-structured ceramics,which their open pores were epitaxially loaded by KN, were prepared with a relative densityof 80 %, and their dielectric constant was 1800 while the piezoelectric constant was 300 pm/V .

首先，制备了相对密度为60%，介电常数为800，压电常数为100 pm/V的钛酸钡（BT）/BT纳米结构陶瓷，其中BT纳米颗粒（尺寸为300 nm）在三维上紧密相连。在此基础上，制备了相对密度为80%的开孔外延负载KN的KN/BT/BT纳米结构陶瓷，其介电常数为1800，压电常数为300 pm/V。
