Abstract:

An apparatus can include a ceramic component, a metal component, and a glass sealing material that bonds the ceramic and metal components to each other. In an embodiment, the coefficients of thermal expansion of the components and glass sealing material can be within 4 ppm/ C. of one another. The metal component may be relatively oxidation resistant. The glass sealing material may have a relatively low amount of an amorphous phase as compared to one or more crystalline phases within the glass sealing material. The apparatuses can exhibit good bond strength even after long term exposure to high temperature, thermal cycling to a high temperature, or both. In an embodiment, the metal component may allow another metal component of a different composition to be used without a significant impact on the integrity of the bonded apparatus.
