采用ＴＥ_１０３单模腔微波炉烧结ＢａＴｉＯ_３系半导体陶瓷，对微波与陶瓷材料相互作用机制进行了探讨，分析了ＢａＴｉＯ_3陶瓷微波结过程中各损耗随温度的变化规律；同时，分别在体系中引入受主杂质Ｃｒ~(３＋)和施主杂质Ｎｂ~(5+)，研究微波场中杂质浓度对钛酸钡陶瓷晶粒生长的影响。
The mechanism of interaction between microwave and ceramic material was studied by using TE_103 single-cavity microwave sintered BaTiO_3-based semiconductor ceramic. The variation of each loss with temperature during the microwave sintering of BaTiO_3 ceramic was analyzed. At the same time, the acceptor impurity Cr 3+ and donor dopant Nb 5+, the effect of impurity concentration in microwave field on the grain growth of barium titanate ceramics was investigated.
