钙钛矿型BiMnO3是同时具有铁磁性和铁电性的多铁性材料,在传感器,信息存储等方面具有潜在的应用前景.但是它的制备条件非常苛刻,需要高温、高压、密封等,这极大地限制了它的应用与发展.本文采用共沉淀法,以MnCl2·4H2O,Bi2O3,NaOH,HNO3和聚乙二醇为材料,在100℃的水溶液中成功地制备出了BiMnO3材料,此方法大大降低了制备的温度和压强,从而节约了能源,降低了成本.同时利用X射线衍射仪(XRD),透射电子显微镜(TEM),振动样品磁强计(VSM)等对其结构、相貌及磁性等进行了检测,并讨论了制备条件及煅烧温度对BiMnO3物性的影响.Perovskite-type BiMnO3, in which ferroelectricity and ferromagnetism co-exist,has potential applications in sensor and information storage. Usually, BiMnO3 is synthesized under high temperature and high pressure in a gold capsule,which restricts its application and development extremely. In this paper, we synthesize the BiMnO3 nanopowders with MnCl2·4H2O,Bi2O3, NaOH,HNO3 and polyglycol at 100 ℃ by the co-precipitation method successfully, in which the conditions of temperature and pressure are reduced, thereby economizing the energy sources and lowering the cost. Their microstructure and magnetic properties are measured by using X-ray diffraction (XRD), transmission electron microscope(TEM) and vibration sample magnetometer(VSM). The effects of synthetical condition and the calcined temperature are also discussed.
