Thin film dielectric composite materials

摘要

A dielectric composite material comprising at least two crystal phases of different components with TiO2 as a first component and a material selected from the group consisting of Ba1-xSrxTiO3 where x is from 0.3 to 0.7, Pb1-xCaxTiO3 where x is from 0.4 to 0.7, Sr1-xPbxTiO3 where x is from 0.2 to 0.4, Ba1-xCdxTiO3 where x is from 0.02 to 0.1, BaTi1-xZrxO3 where x is from 0.2 to 0.3, BaTi1-xSnxO3 where x is from 0.15 to 0.3, BaTi1-xHfxO3 where x is from 0.24 to 0.3, Pb1-1.3xLaxTiO3+0.2x where x is from 0.23 to 0.3, (BaTiO3)x(PbFeo0.5Nb0.5O3)1-x where x is from 0.75 to 0.9, (PbTiO3)-(PbCo0.5W0.5O3)1-x where x is from 0.1 to 0.45, (PbTiO3)x(PbMg0.5W0.5O3)1-x where x is from 0.2 to 0.4, and (PbTiO3)x(PbFe0.5Ta0.5O3)1-x where x is from 0 to 0.2, as the second component is described. The dielectric composite material can be formed as a thin film upon suitable substrates.
