Abstract
Description
圧電層としては、圧電セラミックスが好適に用いられるが、電歪セラミックスや強誘電体セラミックス、あるいは反強誘電体セラミックスを用いることも可能である。具体的な材料としては、ジルコン酸鉛、チタン酸鉛、マグネシウムニオブ酸鉛、ニッケルニオブ酸鉛、亜鉛ニオブ酸鉛、マンガンニオブ酸鉛、アンチモンスズ酸鉛、マンガンタングステン酸鉛、コバルトニオブ酸鉛、チタン酸バリウム、チタン酸ナトリウムビスマス、チタン酸ビスマスネオジウム、ニオブ酸カリウムナトリウム、タンタル酸ストロンチウムビスマス、等を単独であるいは混合物として含有するセラミックスが挙げられる。
長さ5.0mm×幅1.5mm×厚み1.5mmの超音波モーター用圧電素子を、焼成後に1μmとなるようにしたAg−Pd合金電極材料ペーストを、焼成後に10μmとなるようにした圧電グリーンシート上に印刷したものを150層積層したグリーンシート積層体を焼成後、前記外形となるよう機械加工した後、側面電極を形成した超音波モーター用圧電素子を作製した(比較例1)。
上記の実施例1〜10、比較例1と同様にして、超音波モーター用圧電素子を作製した。
これらの素子について、以下の条件で分極処理を行った。
・温度:室温
・入力信号:10kHz 0−250Vパルス波
・時間:60秒
その結果を表2及び図14のグラフに示す。
