本文介绍磁场在水热体系合成粉体以及在固相陶瓷块体织构研究中的应用.水热体系中,磁场引导合成的粉体主要有:Co,Ni等金属粉体,还有Fe3O4,BaFe12O19等铁氧体粉体.固相织构的陶瓷块体有:铁电压电材料,铁氧体磁性材料(包括尖晶石型,石榴石型和磁铅晶石型),还有其他功能陶瓷如α-Al2O3.由于磁场的引导,这些材料都有沿易磁化晶体方向择优生长的特性,并表现出各自优异的性能. In this paper, we introduce the application of magnetic field in synthesis of hydrothermal system powder and in the texture research of solid ceramic block.Water-heat system, the magnetic field-guided synthesis of the main powders are: Co, Ni and other metal powders, as well as Fe3O4, BaFe12O19 and other ferrite powders. Solid-phase textured ceramic blocks are: ferroelectric materials, ferrite magnetic materials (including spinel, garnet and magnetite), as well as other functions Ceramics such as α-Al2O3. Due to the guidance of the magnetic field, these materials have the characteristics of preferentially growing in the direction of easy magnetization and exhibit their excellent properties.
