| 1. A method for preparation of an electrically conducting cermet end cap, the method comprising:
providing predetermined amounts of powders of at least one transition metal element, a garnet; and wherein powders of the
transition metal element have a size less than about 105 micrometers; and the powders of the garnet have a size in a range
from about 100 micrometers to about 1000 micrometers;
mixing together predetermined amounts of powders of at least one transition metal element and a garnet;
compacting the blend to form a desired shape cermet end cap; and
sintering the desired shape cermet end cap at a predetermined temperature for a predetermined period of time.
