Abstract
Description
いる。
(release)のためにも製造され得る。ベリリウムは高蒸発温度と毒性のために、フランシウムおよびラジウムは放射能のために、あまり好ましくはないが、これらの金属の供給装置が本発明により製造されることを排除するものではない。通常の産業用途での使用のために最も好適な金属は、リチウム、ナトリウム、カリウム、ルビジウム、セシウム、マグネシウム、カルシウム、ストロンチウムおよびバリウムである。以下の説明において、簡潔にするために、アルカリおよびアルカリ土類金属は単に蒸発しやすい(evaporable)金属として呼ぶことがある;さらに、以下の説明の部分において、たとえばセシウムの使用について言及がなされるが、いかなる教示も他の蒸発しやすい金属に同様に適用され得る。
セシウム堆積物を完全に囲んでいる。
、連続プロセスの間に行われるのが最良であり、最初に純ゲッター材料の層64を堆積し、層64が所望の所望の厚さに到達すると、所望の蒸発しやすい金属と同一のゲッター材料の共堆積を開始する。
