通过溶胶一凝胶法制取纳米级复合氧化物。用氢气还原复合氧化物获得了超细铁 -硼合金。研究证明 ,反应前体物粒度越大 ,合金中α -Fe含量越高。
Preparation of nano-composite oxide by sol-gel method. Ultrafine iron-boron alloy was obtained by reducing complex oxide with hydrogen. Studies have shown that the larger the particle size of the reaction precursor, the higher α-Fe content in the alloy.
