Abstract

PURPOSE:To obtain a composite piezoelectric unit having high piezoelectric modulus with flexibility by forming the unit in a thin thickness of inorganic series of high piezoelectric constant, uniformly diffusing the organic series having flexibility in the molten unit, and introducing a surface treating agent for enhancing the solubility between both. CONSTITUTION:Ultrafine PZT powder is molten in argon gas of plasma state, and is simultaneously sprayed to a substrate at an ultrahigh speed. At this thime the temperature of the substrate is heated to approx. 550 deg.C, and then a thin piece having crystalline structure exhibiting piezoelectricity is produced. The obtained thin film is isolated from the substrate and is pulverized. The produced thin piece 1 is uniformly dispersed in high molecular piezoelectric unit such as, for example, in molten PVF2, and is then extruded in a sheet shape or is formed in a thin film by a doctor blade method or pressing method. At this time, to enhance the mutual solubility between the thin piezoelectric unit of PZT or the like and the PVF2, a surface treating agent is used at the time of or before dispersing it in the molten material.
