Title: Manufacture of piezoelectric ceramics
Inventor: HONDA KOJI
IPC: H01L41/39
Filed: 1990-02-26
Abstract: PURPOSE:To obtain a ceramic whose orientation property is high by a method wherein temporarily baked piezoelectric ceramic powder is dispersed in a weakly acidic solution, electrode plates are installed in the solution, a voltage is applied to the electrode plates and an aggregate of ceramic particles is formed and baked. CONSTITUTION:Powder 6 formed by crushing temporarily baked piezoelectric ceramic powder is put into and dispersed in a weakly acidic aqueous solution 4. In a state that the ceramic powder 6 has been dispersed as particles 7 in the aqueous solution 4, a voltage is applied to electrodes 2, 3 from a power supply 1. When a voltage which is higher than the bonding strength of the particles 7 and hydroxyl ions OH<-1> is applied between the electrode plates 2, 3, hydrogen ions are adsorbed by the positive electrode plate 3 and the positive side of the spontaneously polarized particles 7 is attracted to the negative electrode plate 2. Thereby, the particles 7 attracted to the electrode plate 2 are oriented completely. An aggregate of the particles 7 which have adhered to the electrode plate 2 is stripped off from the electrode plate 2 and dried; after that, it is baked. Thereby, it is not required to take the trouble to form needle particles, and a piezoelectric ceramic whose orientation property is high can be formed by using ordinary particles.
