ABSTRACT:
A material is provided for producing a hermetic seal with a member made from one of the following: titanium, titanium alloys, platinum, chromel, Alumel, stainless steels and Inconel. The material is particularly adapted to be used with titanium, titanium alloys, Inconel and the 300 series of stainless steels since it has at different temperatures a coefficient of thermal expansion matching changes in the coefficient of thermal expansion of titanium, titanium alloys, Inconel and the 300 series of stainless steels throughout a range of temperatures to approximately 1500.degree. F. The material is partially polycrystalline and partially amorphous and is provided with a high electrical insulation and is impervious to acids and thermal and mechanical shocks. The material may have the following composition:
