A bstract The problem of sealing metals to steatite are similar to those encountered in glass‐metal seals but it is more difficult because four different materials must be joined, namely, steatite, glaze, metal oxide, and metal. The thermal expansion coefficient of these materials must obtain in a certain relationship to guarantee a hermetic seal. The use of high‐chromium steel for sealing purposes and the properties of this steel are described. Some design criteria for hermetically sealing steatite bushings are discussed and hints on manufacturing these bushings are given.
