Glass-or ceramic-to-metal seals

摘要

A method for making a glass-or ceramic-to-metal seal, and the seal itself. A layer of gold is deposited onto the metal. A thin layer of indium is placed over the gold, and the structure is heated above the melting point of indium to create a gold-indium alloy at the gold-indium interface. After cooling, the indium surface of the structure and the glass surface are super-cleaned. The super-cleaned surface are then pressed together to form an air-tight seal.
