摘要
Microwave equipment at 2 450 MHz was employed to prepare BaTiO3. The heating effect of the system in the microwave field, which was influenced by several factors including dielectric properties of synthesis system and thermal insulate structures, was discussed in detail. The heating rates of the synthesis system were mainly determined by BaCO3 and TiO2 at low temperature and by TiO2 and BaTiO3 at high temperature. The results show that the heating effects in microwave field are greatly different from those in conventional furnace. The reaction of BaCO3 and TiO2 only lasts for 3 min at 1 100 degrees C, and the fine, narrow-distributed and well-crystallized powders were prepared.
