摘要： PURPOSE: A piezoelectric valve is provided to minimize the pressure loss of an outlet because a passage of the outlet is not extended even if the outlet is positioned in the center of an actuator. CONSTITUTION: A piezoelectric valve(100) comprises a housing(120) and a piezoelectric actuator(110). The housing comprises an inlet(130), a nozzle(140), an outlet(150), and a passage(145). A chamber(121) is formed inside the housing. The piezoelectric actuator is positioned to cover the upper part of the nozzle. If voltage is applied, the piezoelectric actuator is displaced by bending so that the nozzle can be opened and closed. Both ends of the piezoelectric actuator are not fixed in a chamber. A mounting part(125) is formed in the chamber.

摘要： A method for preparing an MnO2 added PZN-PZT composite is provided to obtain a composite for electronic parts having sufficient dielectric and piezoelectric characteristics including an excellent mechanical quality factor. A method for preparing an MnO2 added PZN-PZT composite comprises the steps of: mixing MnO2 powder with PZN and PZT powder; molding the resultant mixed powder; and sintering the molded product at a low temperature of 1000 deg.C or lower. In the method, MnO2 is added in an amount of 0.1-0.6 wt% based on the weight of the PZN-PZT composite free from MnO2. The raw materials, MnO2, PZN and PZT, are used in such a ratio that the resultant xPZN-(1-x)PZT composite has x ranging from 0.1 to 0.6.
