Abstract :
This work evaluated materials and process interactions in the development of a high density platinum / alumina feedthrough. Effect of Pt particle size, firing rates, firing temperature on the sintering, densification and secondary reactions are evaluated, as well as the effect of alumina additive to minimize the difference in expansion coefficient during cooling.
