| Outline of Final Research Achievements |
A simple method for estimating the formation process of agglomerated particles in an vibrating fluidized bed from the pressure drop in the bed was developed. Moreover, we have succeeded in separating only particles with a single crystalline phase from a mixture of particles having almost equal size and density with different crystalline phases with a certain degree of accuracy.
On the other hand, the effects of microwave heating and pH adjustment on the synthesis of Co, Fe, and Mo composite oxide particles by precipitation method were studied using an experimental setup optimized by simulating the electromagnetic field intensity distribution in a cavity-type microwave heating experimental setup. It was found that the precipitates with the crystalline phase of (Co0.7Fe0.3) MoO4 could be obtained without calcination at adequate pH.
