Description
湿式粉砕混合機として、セラミック製の容量が3リットルのボールミルを用いた。該ボールミルに、あらかじめ分散媒体として直径2ミリのガラス製ビーズを半分量入れ、この中に、焼成原料として、炭酸ナトリウム21.2部、酸化ビスマス93.2部、酸化チタン79.9部、及び炭酸バリウム39.5部を計り取り、更に、媒体としてエタノール600部を入れて、約4時間混合粉砕した。
参考例1で得られた最終の粉末状の焼成物を、更に、工業用水(電導度230μs/cm)を用いて、水相が工業用水の電導度となるまでデカンテーションにより水洗を行った。更に、水洗後に得られた細かな粒径の粉末スラリーを、ろ過、乾燥して、本参考例の粉末状の非鉛系アルカリ含有圧電性物質を得た。得られた粉末について、参考例1の場合と同様にして、電気抵抗率及びろ液のpHを測定したところ、電気抵抗率は1.2×106Ω・mであり、pH値は9.6であった。
本実施例では、原料の混合粉砕及び焼成物の粉砕を乾式法で行った。混合、粉砕には、実験室用小型ポットミルを使用した。該ポットミルに、炭酸ナトリウム21.2部、酸化ビスマス93.2部、酸化チタン79.9部、炭酸バリウム39.5部を計り取り、媒体を使用することなく粉砕混合を行った。次に、得られた混合物を850℃で、4時間かけて焼成を行った。次に、得られた焼成物を再度、上記したポットミルに入れ、粉砕した後、1000℃で3時間焼成を行った。焼成後、約200部の本実施例の粉末状の非鉛系アルカリ含有圧電性物質を得た。
実施例1で得られた最終の粉末状の焼成物を、更に、工業用水(電導度230μs/cm)を用いて、水相が工業用水の電導度となるまでデカンテーションにより水洗を行った。更に、水洗後に得られた細かな粒径の粉末スラリーを、ろ過、乾燥して、本実施例の粉末状の非鉛系アルカリ含有圧電性物質を得た。得られた粉末について、参考例1の場合と同様にして、電気抵抗率及びろ液のpHを測定したところ、電気抵抗率は1.7×106Ω・mであり、ろ液のpH値は9.2であった。
上記した参考例1〜2、実施例1〜2の場合と同様に、市販の鉛系圧電体チタン酸ジルコン酸鉛(PZT)の電気抵抗率及びろ液のpH値を測定した。この結果、電気抵抗率は2.0×106Ω・mであり、ろ液のpH値は8.8であった。
Claims (1)
- アルカリ金属或いはアルカリ土類金属を構成成分として含んでなる圧電性能を有する粉末状の非鉛系圧電性物質を製造する方法において、乾式で原料を充分に粉砕混合した後、該混合物を800〜1100℃で1回目の焼成を行い、更に、得られた焼成物を乾式で粉砕した後、該粉砕物を800〜1100℃で焼成することを1回以上行って結晶性の高い粉末状の焼成物を得、得られた粉末状の焼成物を、水相の電導度が500μs/cm以下となるまで水洗することを特徴とする非鉛系圧電性物質の製造方法。
