Abstract

Effect of glass addition (0.5, 1, 1.5, 2 wt%) on the dielectric, ferroelectric and energy storage properties of barium titanate (BT) ceramic was studied. Phase formation was confirmed by XRD. Lattice parameters were determined by Rietveld refinement and crystallite size, microstrain was determined by W-H plots. Relative density was found to be increasing with addition of glass. Glass addition reduces the dielectric constant of pure BT and maximum value of dielectric constant was found to be 1469 at 1 kHz for 1.5 wt% glass addition. Highest energy efficiency is obtained for 1 wt% glass added BT sample.

钛酸钡加玻璃在储能中的介电和铁电性能研究

摘要

研究了添加玻璃（0.5、1、1.5、2 wt％）对钛酸钡（BT）陶瓷的介电，铁电和储能性能的影响。通过XRD确认相形成。晶格参数通过Rietveld细化和微晶尺寸确定，微应变通过WH图确定。发现相对密度随着玻璃的添加而增加。玻璃添加降低了纯BT的介电常数，并且对于1.5wt％的玻璃添加，发现在1kHz下介电常数的最大值为1469。对于添加1 wt％玻璃的BT样品，可获得最高的能源效率。
