Method for improving dielectric nonlinear dielectricity of barium titanate ceramic by equivalence-acceptor doping
The invention discloses a method for improving dielectric nonlinear performance of barium titanate-based ceramic by equivalence-acceptor doping, which comprises the following steps: weighing BaCO3 powder, TiO2 powder, ZrO2 powder and MnCO3 powder, mixing and grinding to obtain first slurry; drying the first slurry, sieving, and pre-sintering the obtained mixture to obtain first powder; sieving the obtained first powder, adding a medium, and grinding to obtain second slurry; drying the second slurry, adding PVA colloid, and sieving to obtain second powder with the particle size of 60-100 meshes; pressing the second powder into a rough blank by using a tablet press; and sintering the rough blank to obtain the barium titanate-based ceramic sample. The component of the barium titanate-based ceramic sample is Ba (Ti (0.8-x) Mnx) Zr (0.2) 2O3.
公开了等价‑受主掺杂提高钛酸钡基陶瓷介电非线性性能的方法，方法中称量BaCO3、TiO2、ZrO2和MnCO3粉末，混合后研磨得到第一浆料；将第一浆料烘干后过筛，将得到的混合物预烧，得到第一粉料；将得到的第一粉料过筛后加入介质研磨得到第二浆料；将第二浆料烘干后加入PVA胶体过筛得到粒径位于60目‑100目之间的第二粉料；使用压片机将第二粉料压制成粗坯；将粗坯烧结得到钛酸钡基陶瓷样品。钛酸钡基陶瓷样品成分为Ba(Ti0.8‑xMnx)Zr0.2O3。
