摘要： An improvement is obtained in the method for the preparation of pellets of a metal halide as a light-emitting source of metal halide lamps, of which an extremely low moisture content is essential, in order not to increase the moisture content of the metal halide during pulverization and compression molding of the metal halide. Thus, a metal halide dehumidified in advance to have a moisture content not exceeding 5 ppm is pulverized and compression-molded in an atmosphere of an inert gas of which the dew point is -60 °C or lower so that substantially no moisture absorption takes place during processing.

摘要： A precipitation method is proposed for the preparation of a rare earth phosphate powder by the reaction of a water-soluble salt of the rare earth element in an aqueous solution with an ammonium phosphate, which gives a rare earth phosphate powder consisting of non-agglomerate discrete particles having a spherical particle configuration suitable as a base material of rare earth-based phosphors. The method is characterized by the addition of the ammonium phosphate in the form of a powder to an acidic aqueous solution of the rare earth salt under specified conditions in contrast to the conventional method in which the ammonium phosphate is admixed in the form of an aqueous solution.

摘要： An improved method is proposed for the preparation of a strontium-substituted or unsubstituted lanthanum manganite powder by the calcination of a composite carbonate of the respective metallic elements formed by mixing an aqueous solution of a water-soluble carbonate and an aqueous solution of inorganic salts, e.g., nitrates, of the respective metallic elements. Different from conventional procedures in which the aqueous carbonate solution is added to the aqueous nitrate solution of the metallic elements, an unexpected improvement can be obtained in the particle size distribution and particle configuration of the precipitated carbonate and hence of the manganite powder when the aqueous solution of the nitrates of the respective metallic elements is added to the aqueous carbonate solution while maintaining the pH of the precipitation medium in the range from 7 to 9.

摘要： An improved method is proposed for the preparation of a powder of a rare earth oxide having good dispersibility containing no agglomerates of particles even without undertaking disintegration indispensable heretofore. The improved method comprises precipitation of a rare earth carbonate by the admixture of an aqueous solution of an inorganic rare earth salt with an aqueous solution of ammonium hydrogen carbonate in an excess amount over the stoichiometrically equivalent amount to give a slurry of the rare earth carbonate which is subjected to heating treatment in two steps each under specified conditions to effect aging of the carbonate precipitates. Characteristically, the aqueous slurry after the first aging treatment is subjected to an adjustment in three differently specified ways prior to the second aging treatment including, first, admixture of an additional amount of ammonium hydrogen carbonate, second, addition of water to decrease the solid content in the slurry and, third, addition of an inorganic acid to decrease the pH of the slurry.

摘要： An improved method is proposed for the preparation of a composite carbonate powder of lanthanum, cerium and terbium as a base material of a green-emitting phosphor for which the carbonate powder is desired to have a uniform particle size distribution and a particle configuration as close to spherical as possible. The improved method is characterized by two-step heat treatment of the carbonate slurry formed by the addition of, for example, ammonium hydrogen carbonate to a mixed aqueous solution of lanthanum, cerium and terbium nitrates each under specified conditions while the pH of the aqueous slurry is adjusted to 5.0 to 7.5 after the first step heat treatment but before the second step heat treatment.
