Bismuth praseodymium iron cobalt titanium ceramic material with ferroelectricity and ferromagnetism and preparation method of bismuth praseodymium iron cobalt titanium ceramic material
The invention discloses a bismuth, praseodymium, iron, cobalt and titanium ceramic material with ferroelectricity and ferromagnetism. The structural formula of the bismuth, praseodymium, iron, cobalt and titanium ceramic material is Bi < 4 > PrFe < 0.5 > Co < 0.5 > Ti < 3 > O < 15 >. The preparation method comprises the following steps: respectively preparing PrFe0. 5Co0. 5O3 powder and Bi4Ti3O12 powder by adopting a hydrothermal method, mixing the two materials according to a molar ratio of 1: 1, adding absolute ethyl alcohol, grinding and dispersing, carrying out primary annealing reaction in a muffle furnace, cooling, adding absolute ethyl alcohol again, grinding and dispersing, carrying out secondary annealing reaction in the muffle furnace, and cooling, tabletting and sintering after the reaction is finished, thereby obtaining the PrFe0. 5Co0. 5O3/Bi4Ti3O12 composite material. Compared with an existing Bi5FeTi3O15 material, the ceramic material has the advantages that the Bi content in a sample is reduced, the defect concentration of the sample can be effectively reduced, the multiferroic property of the material is improved, and the ceramic material has good ferroelectricity and ferromagnetism at the room temperature and is particularly suitable for being applied to the fields of novel sensors, polypeptide memories and the like.
本发明公开了一种具有铁电性和铁磁性的铋镨铁钴钛陶瓷材料，其结构式为：Bi4PrFe0.5Co0.5Ti3O15。先采用水热法分别制备PrFe0.5Co0.5O3粉末和Bi4Ti3O12粉末，再将这两种材料按1:1的摩尔比混合，然后加入无水乙醇研磨分散，在马弗炉中进行第一次退火反应，冷却后再次加入无水乙醇研磨分散，在马弗炉中进行第二次退火反应，结束后冷却，压片，烧结，即得。相对于现有的Bi5FeTi3O15材料，本发明的陶瓷材料减少了样品中的Bi含量，可有效降低样品缺陷浓度，并且改善了材料的多铁性，该陶瓷材料在室温下具有良好的铁电性和铁磁性，特别适合应用于新型传感器、多肽存储器等领域。
