スタック型アクチエエータに応用した場合、各圧電セラ
ミックス層間の剥離現象を防止できる。Piezoelectric ceramics, which generate distortion when voltage is applied, are used as piezoelectric elements in actuators and the like. Then, rounding is performed to improve the piezoelectric properties of piezoelectric ceramics, and anisotropy is imparted to the electrical properties. That is, by making the piezoelectric constant aSS in the vertical direction much larger than the piezoelectric constant dSt in the lateral direction, the amount of displacement can be increased. In addition, by making d31 relatively small, for example, when applied to a contact type or integrally fired type stacked actuator, it is possible to prevent separation between the piezoelectric ceramic layers.
圧電セラミックスの電気的特性に異方性を持たせる方法
としては次の3つの方法が代表的な方法である。The following three methods are typical methods for imparting anisotropy to the electrical properties of piezoelectric ceramics.
(1) 単軸プレス成形による方法
(2) 針状原料を使用する方法

が記載されている。(1) Method using uniaxial press molding (2) Method using needle-shaped raw materials (3) Method using unidirectional polarization in the firing stage (1)
), for example, Japanese Patent Application Laid-Open No. 60-77307 discloses that the main components are pbo and Ties, and a predetermined amount of G.
A mixed powder containing at least one of the oxides of d, Sm, Nd, and Pr, manganese oxide, and aluminum oxide is press-molded into a disk shape, and after firing at 1200 to 60°C for 5 hours, both sides are coated. A method is described in which an electrode is provided on the substrate and further polarization treatment is performed.

する方法が記載されている。Method (2) can be used in the case of a composite piezoelectric material in which the base material is an organic polymer.
The publication describes a method in which a plurality of piezoelectric fibers having different piezoelectric properties are arranged in parallel in a direction perpendicular to the layer in an organic polymer layer.
更に、方法(3)としては、例えばチタン酸ジルコン酸

記成形体の一1方向に数百v程度の電圧を印加する方法
がある。Furthermore, as method (3), for example, there is a method of applying a voltage of about several hundred volts in one direction of the lead zirconate titanate molded body while heating and firing the molded body at 350 to 1300°C.
しかしながら、特開昭60−77507号公報記載の方
法では非常に小型のものや厚さが薄いものを製造するこ
とは困難であシ、又、焼成温度も高くなる。However, with the method described in JP-A-60-77507, it is difficult to manufacture very small or thin products, and the firing temperature is also high.

維を所定方向に配列しなければならず、製造工程が煩雑
となる。Furthermore, in the method described in JP-A-61-283181, the piezoelectric fibers must be prepared separately and the piezoelectric fibers must be arranged in a predetermined direction during the manufacture of the piezoelectric body, making the manufacturing process complicated.
更K、焼成段階で一分向の分極を行う方法も所望の分極
を起すことは困難である。Furthermore, it is difficult to achieve the desired polarization even in a method in which polarization is performed in one direction during the firing step.
本発明は上記従来技術における問題点を解決するための
ものであり、その目的とするところは小型、軽量で分極
が起シ易し且つ焼成温度が低い圧電セラミックスを容易
に得ることができる製造方法を提供することに6る。The present invention is intended to solve the above-mentioned problems in the prior art, and its purpose is to provide a manufacturing method that can easily produce piezoelectric ceramics that are small, lightweight, easily polarized, and have a low firing temperature. We aim to provide the following.
上記課題を解決するため、本発明の圧電セラミックスの
製造方法は、チタン化合物とジルコニウム化合物と鉛化
合物とを、各金属の比がチタン酸ジルコン酸鉛の組成比

ジルコン酸鉛層を形成し、更に前記操作を繰シ返すこと
によυ、該基板上に複数のチタン酸ジルコン酸鉛層を積
層形成することを特徴とするものである。In order to solve the above problems, the method for manufacturing piezoelectric ceramics of the present invention includes a solution containing a titanium compound, a zirconium compound, and a lead compound such that the ratio of each metal is the same as the composition ratio of lead zirconate titanate. A thin liquid film is formed on the substrate using a liquid thin film, and then a lead zirconate titanate layer is formed on the substrate by drying and heat treatment, and by repeating the above operation, a plurality of titanium It is characterized by forming lead acid zirconate layers in a laminated manner.
チタン化合物、ジルコニウム化合物及び鉛化合物は例え
ば塩類、アルコキシド、錯体などの形態であってよい。The titanium compounds, zirconium compounds and lead compounds may be in the form of salts, alkoxides, complexes, etc., for example.
これらを各金属の比がチタン酸ジルコン[鉛の組成比と
同一となるように含む溶液の溶媒としては、前記各化合

合溶媒を適宜用いる。各化合物の濃度はチタン酸ジルコ

各化合物以外に所望によシ他の化合物を含んでいてもよ
い。As a solvent for a solution containing these metals so that the ratio of each metal is the same as the composition ratio of zirconium titanate (lead), an organic solvent, an inorganic solvent, or a mixed solvent thereof is appropriately used depending on the form of each compound. The concentration of each compound is determined depending on the thickness of the lead zirconate titanate layer (-layer). In addition to the above-mentioned compounds, other compounds may be included as desired.
基材は熱処理の際の温度に耐えられるもの例えばガラス
、セラミックス、耐熱金属である。The base material is a material that can withstand the temperature during heat treatment, such as glass, ceramics, or heat-resistant metal.
基材上に所定厚みの液体薄膜を形成する方法としては慣
用の方法例えば浸漬法、噴霧法、塗布法等を用いること
ができる。As a method for forming a liquid thin film of a predetermined thickness on a substrate, a conventional method such as a dipping method, a spraying method, a coating method, etc. can be used.
液体薄膜を形成した後の乾燥及び熱処理条件は溶媒の種
類や液体薄膜の厚みなどに応じて決定する。Drying and heat treatment conditions after forming the liquid thin film are determined depending on the type of solvent and the thickness of the liquid thin film.
一回の操作で基板上に形成されるチタン酸ジルコン酸鉛
層の厚みが非常に薄い(最大1μm)ので、熱処理にお

秩序に成長するが、厚み方向には1層の結晶層しか形成
されず、このためチタン酸ジルコン酸鉛層を基板上に複
数形成した場合にも全体が配向性の良い結晶の集合体と
なり分極が容易と表るため圧電特性が向上する。Since the thickness of the lead zirconate titanate layer formed on the substrate in a single operation is very thin (maximum 1 μm), crystals of various sizes grow randomly in the direction perpendicular to the thickness during heat treatment. However, only one crystal layer is formed in the thickness direction, so even if multiple lead zirconate titanate layers are formed on a substrate, the whole becomes an aggregate of crystals with good orientation, and polarization is easy. This improves piezoelectric properties.

範囲が広い。As described above, the method for manufacturing piezoelectric ceramics of the present invention involves applying a titanium compound, a zirconium compound, and a lead compound onto a substrate using a solution containing a titanium compound, a zirconium compound, and a lead compound such that the ratio of each metal is the same as the composition ratio of lead zirconate titanate. A liquid thin film is formed on the substrate, followed by drying and heat treatment to form a lead zirconate titanate layer on the substrate, and by repeating the above operation, a plurality of lead zirconate titanate layers are formed on the substrate. Since the layers are laminated, the lead zirconate titanate layer becomes a crystal layer with good orientation, and polarization is easy and there is almost no reed or depolarization, resulting in high reliability. Furthermore, since it can be fired at a lower temperature than conventional methods, the range of selection of base materials is expanded, making it easier to create composites and increasing the degree of freedom in design. Furthermore, since a lead zirconate titanate layer that is thinner and has better electrical properties than conventional methods can be easily obtained, it is effective in reducing the size and weight of electronic components and improving their performance. Further, since the method of the present invention can form a lead zirconate titanate layer on a substrate of any shape, it has a wide range of applications in the case of isobaric application in the production of electronic components.
