摘要： A piezoelectric ceramic which maintains a high piezoelectric property in a composition having MPB structure and has an excellent ability for stabilizing the resonant frequency is provided. The piezoelectric ceramic has a solid solution expressed by the general expression xPbTiO.sub.3 --(1-x) PbZrO.sub.3 as its main component. The value of x in the above general expression causes the piezoelectric ceramic to have a composition having the morphotropic phase boundary structure. A ceramic having a spinel type structure is dispersed within the structure of the piezoelectric ceramic. The amount of the ceramic having the spinel type structure existing in the structure is set at about 5 volume % or less. Co.sub.2 TiO.sub.4, Mn.sub.3 O.sub.4, Fe.sub.3 O.sub.4, Mg.sub.2 TiO.sub.4 and a ceramic having a compound spinel type structure which is a solid solution of them can be used as the ceramic having the spinel type structure.

摘要： A piezoelectric ceramic whose resonance frequency temperature characteristic can be easily adjusted is provided. It contains first and second parts (11 and 12) which can be alternately stacked layers. The first and second parts (11 and 12) are each composed of a compound having a bismuth layer structure, such as a complex oxide containing at least Sr, Bi, and Nb, and have degrees of c-axis orientation different from each other. Since the resonance frequency temperature characteristics change according to the degree of orientation, the first and second parts (11 and 12) having different degrees of orientation are appropriately combined so that the resonance frequency temperature characteristics of the piezoelectric ceramic (2) as a whole is easily adjusted.

摘要： A piezoelectric ceramic composition includes a bismuth layer compound containing at least Sr, Bi and Nb, e.g., (Sr0.9Nd0.1)Bi2Nb2O9, as a main component and 2 parts by weight or less (excluding 0 part by weight), preferably 0.04 part by weight to 0.5 part by weight, of Cu in terms of CuO relative to 100 parts by weight of the main component. From the viewpoint of improvement in sinterability, 0.1 part by weight to 2 parts by weight of Mn in terms of MnCO3 relative to 100 parts by weight of the main component is preferably contained. As a result, it is possible to obtain a piezoelectric ceramic composition resisting no deterioration in piezoelectricity even when a rapid temperature change occurs, and an advantageous piezoelectric component, such as a piezoelectric actuator or a piezoelectric resonator, manufactured using the piezoelectric ceramic composition.

摘要： A piezoelectric element includes a piezoelectric ceramic body containing an internal electrode. The piezoelectric ceramic body is mainly made of a perovskite complex oxide containing an alkali metal niobate-based compound containing at least one element selected from among K, Li, and Na. The internal electrode is made of a base metal material, such as Ni or Cu. The piezoelectric element is produced by co-sintering the internal electrode and the piezoelectric ceramic body. Thus, there is provided an inexpensive piezoelectric element that can be properly used in practice even though it has been fired in a reducing atmosphere.

摘要： Anisotropically shaped ceramic particles are represented by the general formula {(K1−x−yNaxLiy)4(Nb1−zTaz)6O17+aMeOb} (where Me is at least one element selected from the group consisting of antimony, copper, manganese, vanadium, silicon, titanium, and tungsten; and b is a positive number determined by the valence of Me), where x, y, z, and a satisfy 0≦x≦0.5, 0≦y≦0.3, 0≦z≦0.3, and 0.001≦a≦0.1, respectively. The anisotropically shaped ceramic particles have a plate-like shape. The average particle size is 1 to 100 μm, and the ratio D/t of the maximum diameter D of a main surface to the thickness t in a direction perpendicular to the main surface is 2 or more, preferably 5 or more. Thus, anisotropically shaped ceramic particles suitable as a reactive template for preparing a crystal-oriented alkali metal niobate-based ceramic can be produced at relatively low production costs without the need for a complicated production process.
