We were invited for a poster talk at 2013 COMSOL Conference 2013 (Tokyo, 7 Dec.)

熱処理シミュレーションによる酸化物粉末のドーピング効率の向上
Optimization of Post-Heat Treatment for Doping of Metal Oxide Particles

Liquid-to-solid route for preparing a doped metal oxide (powder) shows advantage on the homogeneity of the precursor as well as the product. Heat treatment plays important role in the process where the salt of precursor in the liquid reacts to form metal oxide solid particles and doped with ions of another element. Understanding the effect of heat treatment in the doping process will then give great advantages. In the present study, different heat-treatment profiles had been proposed and applied to increase the efficiency of doping.
