    摘要: An extremely pure powder of an oxide of two or more metals, homogeneous at the atomic level, is shaped and compressed (for example, compacted by cold isostatic pressing) to provide greenware which is sintered to provide finished ceramic articles such as laser cathodes and electrodes for chlorine/caustic electrolysis. For example, pure mixed oxide powder consisting of La 0.7 Sr 0.3 CoO₃ is shaped to a tube, which is cold-­isostatically pressed at 20,000 psi, then sintered to provide a cathode for a CO₂ laser. The starting oxides can be prepared by (1) reacting in water, soluble salts of two or more metals with quaternary ammonium carbonate; the metals being those that form water-insoluble carbonates, thereby to precipitate mixed carbonates of the metals; (2) recovering and drying the precipitate; and (3) calcining the precipitate to provide mixed metal oxides homogeneous at the atomic level and substantially free from extraneous contaminants.

    摘要: 57 A hollow-cathode type metal ion laser (100) for producing white light includes a gas-filled tubular envelope (1) and a hollow-cathode (3) located within the tubular envelope (1). The hollow cathode (3) has holes (4) formed in a side wall portion thereof and a bore therein (3a). The hollow-cathode type metal ion laser preferably includes a plurality of metal-containing reservoirs (7) for diffusing vapour of the metal into the bore (3a) through the holes (4). Each of the metal-containing reservoirs (7) forms a portion of the tubular envelope (1) and is preferably disposed next to one of the holes (4). Further, each of the metal-containing reservoirs (7) preferably extends downwardly. Main anodes (5), one near each of the holes, are preferably disposed one within each of the metal-containing reservoirs (7). The tubular envelope (1) preferably includes sub-anodes (6) disposed one within each end portion (1b, 1c) of the tubular envelope (1) to confine the metal vapour within the bore (3a).
