Description
ある真空蒸着法と異なり、電気メッキ用の簡単な装置を利用するため、単純廉価な装置により超伝導MgB2線材が得られる。しかも、真空蒸着では不可能な基板裏面への成膜も可能であり、コイル状に成形した金属棒に超伝導MgB2膜を付着させ、超伝導マグネットを作製することができる。このような「MgB2電気メッキ法」の利点に加え、本願発明の超伝導MgB2膜の電気メッキによる作製法は、メッキ浴に含まれるMgのモル比を1とした時、0.015〜0.020のモル比でMg(OH)2を添加することにより臨界電流密度(Jc)を飛躍的に向上させる。
cm2、Jc(20K)=140,000A/cm2であった。
Claims (2)
- MgCl 2 (塩化マグネシウム)、KCl(塩化カリウム)、NaCl(塩化ナトリウム)、MgB 2 O 4 (ホウ酸マグネシウム)を混合し、加熱溶融したメッキ浴に、Mg(OH)2(水酸化マグネシウム)が、メッキ浴に含まれるMgのモル比を1とした時、0.015〜0.020のモル比で添加され、メッキ浴に導電体基板を陰極として挿入し、陽極との間に直流電圧をかけ、導電体基板上にMgB2(二ホウ化マグネシウム)膜を形成させることを特徴とする超伝導MgB2膜の電気メッキによる作製法。
- 導電性基板の素材が鉄またはステンレスである請求項1記載の超伝導MgB2膜の電気メッキによる作製法。
