%X The transitional phase appeared when two ferroelectric powders with different Curie point were mixed and sintered together. The characteristics of the transitional phase were related to the original phases. After BaTiO3 (BT) and Pb(Mg1/3Nb2/3)O3 (PMN) were co-fired, the dramatic dielectric-temperature characteristics can be observed. The results show a new phase with a lower Curie temperature (Tc) formed. The Tc of BT raises under the high ambient temperature, which indicates the entrance of the Pb cation into the lattice of BT. The co-fired sample can be prepared with such excellent characteristics, the dielectric constant is more than 3000 at room temperature, the dissipation factor is lower than 60 and the temperature coefficient of capacitance (TCC) accords to the X7R standard.
