  • Hermetic electrical feedthrough comprising a Pt—Ni-based pin alloy
    Patent number: 11990252
    Abstract: A combination of materials and processing parameters have been developed for hermetic seals for electrical feedthroughs in high performance applications. A glass-ceramic forms a hermetic seal between a stainless steel shell and a platinum-nickel-based (Pt—Ni) pin alloy for electrical feedthroughs. The glass-ceramic is processed to develop a coefficient of thermal expansion (CTE) slightly higher than the pin alloy but lower than the stainless steel. The seal system employing the new processing conditions and Pt—Ni-based pin alloy alleviates several problems encountered in previous seal systems and improves the hermetic connector performance.
