采用水热球磨法在170 ℃低温下球磨2 h，不经任何后退火，成功地制备了粒径为100-120 nm的β-LiFe_5 O_8铁氧体。通过XRD、SEM、XPS和磁化测量表征证实了锂铁氧体细颗粒的形成。实验结果有力地支持了球磨不仅能加速固-固反应，而且能加速固-液反应的观点。我们相信，水热球磨可以为低温合成和制造组成和尺寸均均匀的细颗粒开辟一个新时代。(C)2002 Elsevier Science B. V.保留所有权利。
Lithium ferrite, beta-LiFe5O8, fine particles with a 100-120 mn size were successfully prepared by hydrothermal ball milling at the low temperature of 170 degreesC for 2 h without any post annealing. The lithium ferrite fine particle formation was confirmed by characterization using XRD, SEM, XPS and magnetization measurements. The experimental results strongly support the idea that ball milling can accelerate the reaction not only between the solid and solid phases but also between the solid and liquid phases. We believe hydrothermal ball milling can open a new era for the low temperature synthesis and fabrication of homogeneous fine particles both in composition and size. (C) 2002 Elsevier Science B.V.
