Abstract:
In this research,low-voltage electromagnetic compaction is used to compact TiO_(2)powders in the indirect way.After success in making high-density TiO_(2)products by the low-voltage electromagnetic compaction,the effects of coil and field shaper structure on the pressed density and product density have been investigated.If other processing parameters remain constant,the results have shown that,the pressed density and sintered product density increases with the turn number of coil increases,simultaneously,the pore space of product decreases and the grain size of product tends to uniform.In addition,the highest density of pressed parts and products is reached when the taper of field shaper is designed to 45°.
