摘要： A piezoelectric composite material having excellent piezoelectric property and workability, which is prepared by compounding in a specific mixing ratio a ferroelectric ceramic powder comprising microcrystals having uniform size and virtually a single domain and a polymer. The ceramic powder is obtained by preparing a ceramic having a desired composition by causing the appropriate mixture of starting powders to undergo a solid phase reaction, grinding the reaction product, annealing the resulting powder under heat and optionally chemically etching it.

摘要： A sintering temperature can be lowered to 1,200° C. by adding from 15% by weight or more to 35% by weight or less of rutile-type titanium dioxide into forsterite. By carrying out sintering at such a low temperature, a sintered product can be obtained in which sintering was carried out while retaining the respective crystal phases of the forsterite and rutile-type titanium dioxide. Such a sintered product is an excellent high-frequency ceramic composition, wherein the high quality factor Q·f value derived from forsterite is hardly impaired, and, the absolute value of the temperature coefficient τf is controlled to 30 ppm/° C. or less by rutile-type titanium dioxide.
