Effect of metallic ions on dispersibility of fine diaspore ZHOU Yu-lin, HU Yue-hua, WANG Yu-hua School of Resources Processing and Bioengineering, Central South University, Changsha 410083, China Received 24 May 2010; accepted 30 August 20a10 Abstract: Dispersion experiments were conducted to study the influence of metallic cations on the dispersibility of diaspore. The reaction mechanisms......
, the effects of electrolytes on the dispersibility of ferrofluid in the dispersing system with different pH values were discussed. The ζ-potential of magnetic nano-particles was measured to discover the adsorbent state of oleate group on the surface of magnetite particles. The mechanism that coexisting electrolyte influences the dispersibility was studied. The results show that the electrolyte affects......
