钙钛矿型弛豫铁电体NbNb13Nb2O3是一种重要的电致伸缩材料，具有较高的介电常数和较大的电致伸缩应变。然而，由于焦绿石相的稳定形成，很难制备成多晶陶瓷形式。研究了焙烧过程中的反应动力学，提出了一种改进的制备方案。
The perovskite relaxor ferroelectric lead magnesium niobate (PbMg 1 3 Nb 2 3 O 3) is an important material because of its high dielectric constant and correspondingly large electrostrictive strains. However, it is difficult to prepare in polycrystalline ceramic form because of the formation of a stable pyrochlore phase. The reaction kinetics during calcining were investigated and an improved fabrication scheme was developed.
