Aluminum Oxide and Beryllium Oxide Ceramics — Seal Materials of the Future

The temperature dependence of various physical properties of alumina and beryllia ceramics are presented along with some important chemical and nuclear considerations. Properties in the cryogenic temperature regions are stressed. The data presented will be a composite of information gained in the Research Laboratory of Coors Porcelain Company and from literature sources on cryogenic properties of alumina and beryllia material.
