Interfacial Reactions in Ceramic-Metal Systems.

摘要

Ceramic-metal and ceramic-ceramic joining are enabling technologies that allow the superior properties of ceramics to be exploited in areas where they otherwise might not be suited. More economical manufacture of complex structures, hermetic metal-insulator seals, metal-ceramic composites, and packaging of electronic devices are examples for which availability of ceramic-metal and ceramic-ceramic joining is critical to function. Rational control of ceramic joining requires an understanding of reaction and bonding mechanisms. This paper very briefly reviews the thermodynamic basis of wetting, adhesion, and interfacial reactions. Those general principles are used to interpret experimental results from three examples of ceramic-metal reactions relevant to joining and electroding: (1) glass-ceramic to metal reactions; (2) Si3 N4 -braze alloy reactions; and (3) AlN-metallization reactions. 35 refs., 11 figs., 3 tabs.
