Zinc powders were firstly modified by mechanic-chemistry method using titanate coupling agent,silane coupling agents and sodium dodecylbenzenesulfonate.Their dispersion stabilities were investigated via measuring the height with the sedimentation method.The results showed that different species and concentrations of surface modifier have dramatic effects on the dispersion stability.The dispersion stability of the zinc powder modified by 1.0% titanate coupling agent was significantly improved and close to that of imported zinc powder.
