Description
30wt%のAg及び70wt%のAlを有するAg−Al合金を、米国特許出願公開第2006/0112785号に記載されているように生成し、そしてストリップ状に形成した。そのストリップの一部を、NaOHで事前洗浄し、秤量し、そして垂直の管状のるつぼ形炉に配置した。その管状のるつぼ形炉を、その後、炉の垂直な外側管の内部に配置し、950℃まで加熱した。この温度は、その合金の相図から決められる選択した組成物の融点より高くするように選ばれた。また、アルゴンを、内側管の上部にある供給口を通じて、550℃の温度に到達するまで、時々且つ手短に供給した。内側管の下部にある排出口を、液体窒素の供給により内部から冷却した約60cmの直径を有する銅の回転ホイール(「冷却ホイール」)の約0.5〜0.75cmすぐ上に配置した。その冷却ホイールの回転スピードを、外部のモーターによって制御した。
30wt%のAg及び70wt%のAlを有するAg−Al合金を、実施例1に記載したように生成し、そしてストリップ状に形成した。そのストリップの一部をNaOHで事前洗浄し、秤量し、そして垂直の管状のるつぼ形炉に配置した。その管状のるつぼ形炉を、その後、炉の垂直な外側管の内部に配置し、850℃まで加熱した。また、アルゴンを、内側管の上部にある供給口を通じて、550℃の温度に到達するまで、時々且つ手短に供給した。内部配管の下部にある排出口を、冷却ホイールの約0.5〜0.75cmすぐ上に配置した。
異なるバッチに対し異なる浸出時間(45分、90分、180分及び24時間の浸出)を用いたことを除いて、実施例1を本質的に繰り返した。
