Description
本発明は下記の実施例によってさらに明確になるであろう。
(1)濾過された清潔な雰囲気中で厚さ125μmの「テフロン」フィルムをガラス板上に平らに伸ばし、このガラス板にテープで取り付け、
(2)50μmのギャップと15cmの幅とを備えたドクタ・ブレードを用いて、「テフロン」でコーティングされた布の上にジルコニア・3モル%イットリア粉末からなるスリップをコーティングして、生のプレ・セラミックシートを形成し、
(3)この生のシートを室温でプラスチックカバーの下で30分間乾燥させた。このプラスチックカバーは、セラミックシートの幅に沿って約2mmのギャップを有するが長いエッジに沿うギャップはなしに乾燥させている生のプレ・セラミックシートを包み、
(4)次にこの生のシートを60℃の炉内で1時間乾燥させ、
(5)この生のシートを、例えば図6の電解質シート10に対応する波型パターンを有する型により上述した真空成形法を用いて波型を付し、
(6)最後に、波型を付された生のシートを1430℃で2時間焼成した。
