Claim 10:
11. A method of preparing a wettable substrate, comprising:
q) verifying the existence of an open-cell pore network in a ceramic substrate desired to me wetted with a first metal;
r) evacuating air from the open-cell pore network;
s) infiltrating the open-cell pore network with a second metal to yield an infiltrated substrate, wherein the second metal is disposed entirely within the open-cell pore network;
t) heating the infiltrated substrate to exude second metal from the open-cell pore network to produce a second metal coating over the infiltrated substrate to yield a coated substrate;
u) wetting the coated substrate with the first metal to yield a wetted substrate;
wherein the first metal has a first melting point; and
v) cooling the substrate to draw the exuded second metal back into the open-cell pore network;
wherein the second metal has a second melting point; and
wherein the ceramic substrate has a sintering temperature greater than the respective melting points of the first and second metals.
