Barium ferrite ceramic material and preparation method thereof
The invention relates to a barium ferrite ceramic material and a preparation method thereof. The preparation method comprises the following steps of: 1) mixing a barium precursor solution and an ironprecursor solution, and then adding a precipitant to obtain a precipitate; 2) calcining the precipitate at the temperature of 400-450 DEG C; 3) calcining the precipitate at the temperature of 800-850DEG C; 4) grinding the precipitate, and calcining the ground precipitate at 1250-1300 DEG C in an oxygen atmosphere; and 5) annealing the precipitate in an oxygen atmosphere at 700-820 DEG C to obtainthe barium ferrite ceramic material. The invention also comprises a barium ferrite ceramic material prepared by the preparation method. The invention also comprises a barium ferrite ceramic materialprepared by the preparation method. The barium ferrite ceramic material is an M-type barium ferrite ceramic material, shows intrinsic multiferroic property, and has relatively strong ferroelectric andferromagnetic and magnetoelectric coupling effects at room temperature.
本发明涉及一种钡铁氧体陶瓷材料及其制备方法。该制备方法包括：1)将钡前驱体溶液和铁前驱体溶液混合，之后加入沉淀剂得到沉淀物；2)将沉淀物在400‑450℃下煅烧；3)将沉淀物在800‑850℃下煅烧；4)将沉淀物研磨，将研磨后的所述沉淀物在1250‑1300℃及氧气气氛下煅烧；5)所述沉淀物在氧气气氛及700‑820℃下退火处理得到所述钡铁氧体陶瓷材料。本发明还包括上述制备方法制备得到的钡铁氧体陶瓷材料。本发明还包括上述制备方法制备得到的钡铁氧体陶瓷材料。该钡铁氧体陶瓷材料为M型钡铁氧体陶瓷材料，该材料显示出了内禀的多铁性，且在室温下有较强铁电与铁磁性和磁电耦合效应。
