ABSTRACT:
A material hermetically seals two members. One member may be titanium or a titanium alloy and the other member may be a noble metal such as platinum. The seal is resistant to acids and alkalis and is substantially impervious to shocks resulting from mechanical forces or abrupt changes in temperature. The material includes a pair of fluxes having different melting temperatures and a stuffing material including the oxides of zinc and zirconium. The oxides of zinc and zirconium become crystallized at the surface between one of the members and the material. An oxygen valence bond is also produced between the material and such member. The material is more amorphous at the boundary with the second member than at positions removed from such member. The material is formed by progressive heatings for at least a pair of periods of time insufficient to crystallize all of the material and by rapid coolings of the material after each of such heatings.
