Abstract

PURPOSE: To obtain a composite, which can be sintered at a low temperature, with a higher dielectric constant and less dielectric loss by specifying a composition range of three-component system of Pb(Fe1/2Nb1/2)O3, Pb(Mg1/3Ta2/3)O3 and Pb(Co1/3Nb2/3) O3.
CONSTITUTION: The composite consists of 60.71 to 67.57 weight % of PbO, 1.78 to 11.41 weight % of Fe2O3, 5.42 to 25.40 weight % of Nb2O5, 0 to 2.56 weight % of MgO, 0 to 28.05 weight % of Ta2O5 and 0 to 6.32 weight % of CoO, its composition is shown in the area surrounded by a quadrilateral ABCD in the three-component system diagram of Pb(Fe1/2Nb1/2)O3 - Pb(Mg1/3Ta2/3)O3 - Pb(Co1/3Nb2/3O3. But a com position on the two-component line such as Pb(Fe1/2Nb1/2)O3 - Pb(Mg1/3 Ta2/3)O3 and Pb(Fe1/2Nb1/2)O3 - Pb(Co1/3Nb2/3)O3 is excluded. A material combined in the said composition area is calcined at 700 to 850°C, grinded again, molded after addition of caking agent, and is fired at 850 to 950°C.
