摘要： A glass-to-metal seal including a metal member such as Pd or a Pd-Ru alloy and a glass member wherein the glass member is in contact with the metal member and forms a glass-to-metal seal therewith. The seal can include an outer body surrounding the glass member and forming a seal therewith. The outer body has a coefficient of thermal expansion greater than that of the glass member and the seals between the outer body, the glass member and metal member are compression seals. The glass-to-metal seal is made by directly glassing onto the metal member in a furnace having an atmosphere which prevents outgassing of hydrogen from the metal member into the interface between the glass member and metal member. After the glass-to-metal seal forming step, the outer body can be metallurgically bonded to another component without chemically cleaning the outer body and the metal member can be metallurgically bonded to another member such as a gold wire without plating the metal member prior to the bonding step.
摘要翻译：包括诸如Pd或Pd-Ru合金的金属构件的玻璃 - 金属密封件和玻璃构件，其中玻璃构件与金属构件接触并与其形成玻璃 - 金属密封。密封件可以包括围绕玻璃构件并与其形成密封的外部主体。外体的热膨胀系数大于玻璃构件的热膨胀系数，外体，玻璃构件和金属构件之间的密封是压缩密封。玻璃 - 金属密封件通过在具有防止氢从金属部件逸出到玻璃构件和金属构件之间的界面的气氛的炉子中直接玻璃化到金属构件上而制成。在玻璃 - 金属密封形成步骤之后，外部体可以冶金地结合到另一个部件上，而不用化学地清洁外部本体，并且金属部件可以冶金地结合到诸如金线的其它部件上，而不会在金属部件之前镀覆金属部件接合步骤。
