Description
好ましくは、保持ユニットはリング状に形成され、より好ましくは内側に溝を有するリング状ユニットである。
・所定の場合に、担体の基材として働くスポンジ及び/又は顆粒及び/又は繊維材料を平均粒径又は平均直径に基づいて2以上の画分に分割する。及び
・個々の画分を計画された層の数に従ってプレス器具内でそれぞれの頂部に積層し、その後コールドプレス又は焼結する。
1.O2フリットプレス
2.洗浄、検査
3.組立
実際は、2層から成るフリットである。リブ付きの側では、粗粒チタン粉末(粒径:400〜1000μm(4×10−4m〜1×10−3m))4.5gを使用する。一方、膜と接触する側では、微細粒チタン粉末(粒径:400μm未満(4×10−4m未満))0.5gを使用する。よってそれらの総重量は5.0gである。
チタンと接触する器具の表面を、アルコールに浸漬した人工綿で又は10% HCl溶液で洗浄し、蒸留水ですすぎ、そしてすばやく乾燥する。
作成済みのプラスチックリングをプレス器具の下部に配置する。その後、粗粒チタン粉末をプレス器具内に均等に流し込み、粉末を適当な器具を用いてやさしく広げる。その後、器具を水平に保持して器具を回転させながら、混合物を分配する。
プレス棒をプレス器具内に配置し、チタン粉末をプレスする。操作後、プレス棒をプレス器具から除去する。次の工程では、微細粒チタン粉末をプレス器具に流し込み、広げる。分布後、プレスインサートをプレス器具上部内に配置し、チタン粉末をプレスする。
プレス器具をプレス内に配置し、10トン(1×107g)の重量でプレスする。プレスを開き、プレス器具を取り出す。プレス器具を分解し、プレスされたフリットをプレス器具から叩き出す。プレス後、プレスされたフリット及びプレス器具を圧縮空気で洗浄する。
プレスされたフリットをエタノール中に15分間浸漬し、その後乾燥した。任意の考えられるチタン粒子をフリットの両面から除去し、表面の平滑度を検査した。
O2フリットを、平滑面を上向きにした人工綿上に配置した。イリジウム懸濁液(80mg/ml)500μl(5×10−4l)をフリットのチタン部分にプレスした。さらに、先の操作を、さらにかかるイリジウム懸濁液500μl(5×10−4l)を用いて繰り返し、そして乾燥した。イリジウムでコーティングした電極を、水圧プレスを用いて2トン(2×106g)で懸濁液側にプレスした。
