摘要
微细钴粉由于其特殊的物理、化学性能,在硬质合金、电池、催化剂、磁性材料、吸波材料、陶瓷等领域的应用中表现出许多优异的性能。本试验采用硫酸钴为原料、水合肼和SBH的混合溶液作为还原剂,探讨了在弱碱性条件下微细钴粉的制备,并对其反应机理进行了分析。
Fine cobalt powder has been widely used in hard alloy,battery,catalytic agent,magnetic materials,wave-adsorbing materials and ceramics for its specific physical and chemical properties.A new method for preparation of fine cobalt powder is discussed in this paper when hydrazine is used as deoxidizer while SBH is used as additive.
