摘要： Ultra-fine hollow glass spheres suitable as a filler in light-weight composite materials for building use and the like can be prepared from a fine powder of volcanic glass even when the starting powder has a particle size as fine as 20 .mu.m or smaller. The inventive method comprises an acid-leaching treatment of the starting powder using hydrochloric or sulfuric acid under hydrothermal conditions at 150.degree.-200.degree. C. to modify the chemical composition in the surface layer of the particles and a subsequent heat treatment of the acid-treated particles at a specified high temperature to effect expansion by the water vapor produced from the structural water in the softened particles. By virtue of the modified composition in the surface layer and in contrast to the prior art method without the acid treatment, a good balance can be obtained between the rate of water vapor release and softening of the particles even when the particle size is extremely small to facilitate expansion of the particles.

摘要： A lower electrode is formed on a silica glass substrate or a stainless substrate. Through a sputtering process, a thin film of aluminum nitride and/or zinc oxide is formed on the lower substrate so that the degree of dipole-orientation becomes 55% or more, and thereby a piezoelectric thin film is formed. And an upper electrode is formed on the piezoelectric thin film.A piezoelectric device has a piezoelectric layer made of aluminum nitride and/or zinc oxide. Aluminum nitride and zinc oxide with a crystal structure have inborn piezoelectric characteristics because their crystal structures are not symmetrical, they do not have Curie temperature unlike ferroelectrics, and in aluminum nitride and zinc oxide, magnetic transition does not occur even at high temperature, so that they never lose piezoelectric characteristics until crystal melts or sublimates.
摘要翻译： 在石英玻璃基板或不锈钢基板上形成下电极。 通过溅射工艺，在下基板上形成氮化铝和/或氧化锌薄膜，使得偶极取向度达到55％以上，从而形成压电薄膜。 并且在压电薄膜上形成上电极。 压电装置具有由氮化铝和/或氧化锌制成的压电层。 具有晶体结构的氮化铝和氧化锌具有先天的压电特性，因为它们的晶体结构不对称，它们不像铁电体那样具有居里温度，并且在氮化铝和氧化锌中，即使在高温下也不会发生磁转变，因此 在晶体熔化或升华之前，它们不会失去压电特性。

摘要： A thin film made of a wurtzite structure compound is manufactured by a reactive sputtering using a metal material as a target, and a nitrogen gas or oxygen gas as a reactive gas. By optimizing film-forming conditions when manufacturing the film, it is possible to obtain a wurtzite thin film whose polarization directions of crystal grains are aligned in a uniform direction. There is provided a laminate including a first wurtzite crystalline layer made of a wurtzite crystalline structure compound is formed in advance between a substrate and a functional material layer that is a ground. Thus it is possible to improve the crystallinity and crystalline orientation of a second wurtzite crystalline layer on the functional material layer.

摘要： A stacked structure (1) includes an electrostriction layer (2) including an electric inductive distortion material and a stress light-emitting layer (3) including a stress light-emitting material. When applying a voltage to the electrostriction layer (2) in the stacked structure (1), the electric inductive distortion material deforms, thereby the electrostriction layer (2) deforms. The deformation of the electrostriction layer (2) causes an external force to act on the stress light-emitting material of the stress light-emitting layer (3), and the stress light-emitting layer (3) emits light, accordingly. That is, by applying the voltage to the stacked structure (1), the stacked structure (1) can emit the light.
