Abstract: The elastic modulus of a piezoelectric substance is controlled over a wide range using a simple method. The effective modulus (the real part of the elastic modulus) and the energy loss modulus (the imaginary part of the elastic modulus) of the piezoelectric substance are changed by installing electrodes on the surface of the piezoelectric substance and by connecting a mechanism consisting of one or more circuit elements to each of the electrodes.

Abstract: Proposed is a powder consisting of rare earth oxide-based composite particles having an average particle diameter in the range from 0.1 to 100 .mu.m, each of which has a composite structure consisting of a core of a rare earth oxide and a coating layer of a rare earth hydroxide, the coating layer of the rare earth hydroxide having an average thickness of at least 5 nm but not exceeding 10% of the average particle diameter of the composite particles. While a rare earth oxide powder is useful as a sintering aid of a ceramic powder which is used in molding usually in the form of an aqueous slurry, the composite particles when added to an aqueous slurry of a ceramic powder exhibit a remarkable effect as a viscosity stabilizer or gelation inhibitor of the aqueous slurry so that improvements can be obtained in the productivity of the manufacturing process and quality of ceramic products.

Abstract: Proposed is a powder of ytterbium phosphate having a non-stoichiometric phosphorus to ytterbium molar ratio of 1.08 to 2.0 and having a specified average particle diameter and specified diameter of the crystallites forming the particles.

The ytterbium phosphate powder can be prepared in a convenient and inexpensive method utilizing the precipitation reaction by mixing an aqueous phosphoric acid solution and ytterbium salt solution under specified conditions followed by calcination of the precipitates at a specified temperature and pulverization of the calcined precipitates to give the specified average particle diameter.

Abstract: An improvement is proposed in the so-called urea method for the preparation of fine particles of yttrium oxide, according to which, while an aqueous reaction mixture containing a water-soluble yttrium salt, e.g., nitrate, and urea dissolved therein in specified concentrations is heated at 90.degree. to 100.degree. C. to effect precipitation of yttrium carbonate hydroxide particles followed by calcination of the carbonate hydroxide in air into yttrium oxide, the aqueous reaction mixture is diluted with addition of a specified volume of preheated water within a critical period between incipient appearance of turbidity in the reaction mixture by the precipitation of the carbonate hydroxide and a moment 30 minutes thereafter. In this way, the yttrium oxide particles obtained have a globular particle configuration with a very small average particle diameter D.sub.50 in the range from 0.1 to 0.3 .mu.m and are suitable for use in various fine applications.
