Anti-ferroelectric ceramic film slurry and preparation method thereof
The invention relates to anti-ferroelectric ceramic film slurry and a preparation method thereof. The anti-ferroelectric ceramic film slurry comprises 8 parts of lead lanthanum zirconate titanate powder, 4 parts of a first organic solvent, 1 part of a first adhesive, 1 part of a first dispersant, 1 part of a first plasticizer and 1 part of a second plasticizer. In order to optimize the properties of the slurry, the adhesive and the plasticizer are added into the slurry, so that the viscosity, the field angle and the smoothness of the slurry are remarkably improved, the slurry can be uniformly and smoothly spread in a large area, the prepared anti-ferroelectric ceramic film is flat in diaphragm and uniform in thickness, and the minimum thickness can be within 10 microns. Moreover, an anti-ferroelectric ceramic capacitor green body prepared from an anti-ferroelectric ceramic thin film prepared from the slurry is better in quality, the corresponding plastic removal time is shorter, and the quality and hardness of a ceramic finished product are better.
本申请涉及一种反铁电陶瓷薄膜浆料及其制备方法，包括锆钛酸铅镧粉末8份、第一有机溶剂4份、第一粘合剂1份、第一分散剂1份、第一塑化剂1份和第二塑化剂1份。本申请为了优化浆料的性质，在浆料中添加了粘合剂和塑化剂，这使得浆料的粘度、张角和平滑度都得到了显著提升，让浆料能够均匀且平滑地大面积铺展开来，制备出的反铁电陶瓷薄膜，膜片平整，厚度均匀，最薄可以做到10um之内。不仅如此，利用本申请浆料制备而成的反铁电陶瓷薄膜制作出的反铁电陶瓷电容生胚，质量更好，相应的排塑时间更短、陶瓷成品质量和硬度更优。
