Title

Reactions and Bonding Between Glasses and Titanium

Abstract

Hermetic seals between titanium and both silicate and alkaline earth boroaluminate glasses have been made. Mechanical testing of pin seal configurations indicate that the boroaluminate glass seals are at least 50% stronger than the silicate glass seals. To explain these differences, the interfacial chemistries of the two systems were characterized by a number of techniques, including x-ray photoelectron spectroscopy (XPS). Titanium silicide and titanium boride phases were found, respectively, at the silicate and boroaluminate titanium interfaces. It was found that the rapid development of a relatively thick silicide interfacial phase adversely affects the strength of a silicate glass titanium seal, while the formation of a thinner boride phase does not affect the properties of the boroaluminate glass seals.
