Manufacture and use of ZrB2/Cu or TiB2/Cu composite electrodes

The invention relates to ZrB2/Cu composites, and more specifically to methods of making ZrB2/Cu composite electrodes and methods of using ZrB2/Cu composite electrodes. ZrB2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB/2 powder is sintered. The...

More Information
Summary:The invention relates to ZrB2/Cu composites, and more specifically to methods of making ZrB2/Cu composite electrodes and methods of using ZrB2/Cu composite electrodes. ZrB2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB/2 powder is sintered. The sintered ZrB2is contacted with Cu and heated above the melting point of Cu which causes the Cu to infiltrate the ZrB2, forming the ZrB2/Cu composite electrode.
