Abstract: A particle free device for releasing a metal vapor, such as cesium or mercury, which comprises a vapor permeable particle free envelope and a metal vapor releasing substance within the envelope. This substance can be a mixture of a metal compound and reducing agent for the compound, or can be a material such as a metal oxide which releases its metal upon heating. The devices can have a resistance heating unit in thermal proximity to the metal vapor releasing substance. These devices are useful for the introduction of metal vapors into vessels such as electron tubes.
Abstract translation: 用于释放诸如铯或汞的金属蒸气的无颗粒的装置,其包括透气无颗粒的外壳和在外壳内的金属蒸气释放物质。 该物质可以是化合物的金属化合物和还原剂的混合物,也可以是加热时释放金属的金属氧化物等材料。 这些装置可以具有与金属蒸气释放物质热接近的电阻加热单元。 这些装置可用于将金属蒸汽引入诸如电子管的容器中。
