Preparation method of tetragonal-phase barium titanate ceramic powder with antibacterial property
The invention discloses a preparation method of tetragonal-phase barium titanate ceramic powder with antibacterial performance, and belongs to the technical field of ferroelectric and piezoelectric ceramic materials. The method comprises the steps: completing atomic-scale mixing of a barium source and a titanium source in a liquid-phase state by means of a liquid-phase chemical process; then, fixing the mixture in the form of a liquid precursor through a rotary evaporation reaction; and finally, carrying out a certain heat treatment process on the washed and dried precursor, thereby controllably synthesizing the tetragonal-phase barium titanate ceramic powder with good antibacterial performance. In the synthesis process, common inorganic salts and simple reagents are mainly used, so that the method is low in cost, simple and easy to implement and good in repeatability. The synthesized tetragonal-phase barium titanate ceramic powder is stable in component, narrow in size and particle size distribution, high in crystal face index, good in antibacterial performance and suitable for large-scale batch production, and a certain theoretical basis is provided for antibacterial research of ferroelectric materials.
本发明公开了一种具有抗菌性能四方相钛酸钡陶瓷粉体的制备方法，属于铁电、压电陶瓷材料技术领域。该方法借助液相化学过程，将钡源和钛源在液相状态下完成原子尺度的混合；再次，通过旋转蒸发反应将其以液态前驱体的形式固定下来；最后，洗涤干燥后的前驱体通过一定的热处理工艺，从而可控合成具有良好抗菌性能四方相钛酸钡陶瓷粉体。合成过程中主要以常见的无机盐和简单的试剂为主，成本低，简单易行且重复性很好。合成的具有四方相钛酸钡陶瓷粉体成分稳定、尺寸粒径分布较窄、晶面指数高、抗菌性能好、适合大规模批量生产，为铁电材料抗菌研究提供一定的理论依据。
