Manufacture and use of ZrB.sub.2 /Cu or TiB.sub.2 /Cu composite electrodes

摘要

The invention relates to ZrB.sub.2 /Cu composites, and more specifically to methods of making ZrB.sub.2 /Cu composite electrodes and methods of using ZrB.sub.2 /Cu composite electrodes. ZrB.sub.2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB/.sub.2 powder is sintered. The sintered ZrB.sub.2 is contacted with Cu and heated above the melting point of Cu which causes the Cu to infiltrate the ZrB.sub.2, forming the ZrB.sub.2 /Cu composite electrode.
