    摘要： A diamond electrode comprises a polycrystalline mass of diamond particles bonded together and has a porous surface, or an at least partly porous surface. The porous surface of the electrode is typically created by leaching non-diamond material, such as a second phase of a metallic material, at least in part, from the bonded polycrystalline mass of diamond particles, either before or after shaping it into an electrode. Alternatively, or additionally, the porous surface of the electrode may be created by subjecting a mass of diamond particles to conditions of elevated temperature and pressure to self-bond the particles together in the absence of a second phase.

    摘要： The invention relates to a boron carbide composite material comprising diamond particles and boron carbide, the composite material having a porosity of less than 2 percent by volume. The invention further relates to a method for manufacturing such materials, the method including coating a plurality of diamond particles with boron carbide, combining the plurality of diamond particles to form a green body and subjecting the green body to a temperature in the range from about 1,200 degrees centigrade to about 2,000 degrees centigrade and pressure or vacuum not exceeding about 2,000 Mpa.
