Summary

The fabrication of glass-ceramic to metal components has classically been a two-dimensional process based on the control of time and temperature to yield high-quality components. The implementation of hot isostatic pressing (HIP) to the manufacturing of glass-ceramic to metal seals adds a third dimension (i.e., pressure) to the process. HIP processing of a multiconstituent, lithia-alumina-silica glass at high pressures, up to 207 MPa (30 000 psi), was shown to control the crystalline phases that form in the glass-ceramic. In addition, the high-pressure processing of components fabricated with the glass-ceramic and several high tensile strength alloys, Inconel 718, Hastelloy C-276, Inconel 625, and Nitronic 40, was found to yield superior pore-free interfacial seals with improved hermeticity.
