Abstract

Physical and chemical bases of ferroelectrics with the controlled multilayers are studied to design a capacitor with the high and flat dielectric constant. Each component, (1 - x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (x = 0, 0.1 and 0.2), is compounded in parallel at the stage of a green compact and sintered at 1200°C for 2 h. The ceramics exhibits the flat dielectric curve at temperatures between - 10 and 100°C with the dielectric constant, 9 × 103. The flat dielectric curve is attributed to the existence of the reaction layer formed during sintering between the parallel segments with different x.
