CaCu_3Ti_4O_12/CaTiO_3 Composite Dielectrics: A Ba/Pb-free Ceramics with High Dielectric Constants

W. Kobayashi, I. Terasaki

We have measured dielectric properties of Ca${}_{1+x}$Cu${}_{3-x}$Ti${}_4$O${}_{12}$ ($x$ = 0, 0.1, 0.5, 1, 1.5, 2, 2.9 and 3), and have found that Ca${}_2$Cu${}_2$Ti${}_4$O${}_{12}$ (a composite…
