【Abstract】 Base on the analyses of the interaction between synthesis system materials and microwave field,the heating mechanism in the microwave field was studied.The heating rates of the synthesis system were mainly determined by SrCO3 and TiO2 during low temperature range,and by TiO2 and SrTiO3 at high temperatures.The results show that the heating effects in microwave field are guite different from that in conventional furnace.The heating effect of the system in the microwave field which was influenced by several factors including dielectric properties of the synthesis’s system and thermal insulate structures was discussed in detail.更多还原
