华东冶金学院化工系无机非金属材料教研室经过多年努力 ,已成功地制备出多种铁酸盐纳米粒子材料。新研制的制备工艺所需设备简单 ,操作方便 ,适宜工业化生产。在焙烧温度为 50 0～60 0℃时 ,各种样品粒径分别在 30～ 50ｎｍ范围 ,粒度均匀。发展纳米技术是一个系统工程 ,需要多 East China Institute of Metallurgical Chemical Engineering Department of inorganic non-metallic materials, after years of efforts, has successfully prepared a variety of ferrite nanoparticles material. The newly developed preparation process required equipment is simple, easy to operate, suitable for industrial production. At the calcination temperature of 50 0 ~ 60 0 ℃, the particle sizes of various samples are in the range of 30 ~ 50 nm, respectively, with uniform particle size. Developing nanotechnology is a systematic project that takes more
