摘要： A process is disclosed for removing potassium from relatively impure molybdenum trioxide. The process involves contacting the impure molybdenum trioxide containing greater than about 600 weight parts potassium per million with a first acid leach which consists essentially of nitric acid and ammonium nitrate at a temperature of at least about 50.degree. C. for a sufficient time and at above a 2 molar concentration of said nitric acid and an ammonium nitrate concentration of from about 1.5 to about 2 molar in said first acid leach to solubilize the major portion of the potassium and form a once leached molybdenum trioxide containing the remaining portion of the potassium which is separated from the resulting potassium containing acid leach and contacted with a second leach solution substantially similar to the first acid leach followed by separating the resulting twice leached molybdenum trioxide from the resulting potassium containing second leach. The twice leached molybdenum trioxide is contacted with sufficient water to remove any residual impurities followed by removal of the resulting wash water.

摘要： A process is disclosed for producing ammonium tetrathiomolybdate. The process involves reacting an ammoniacal molybdate solution with hydrogen sulfide gas, the solution and the gas being in a closed system and the flow of the gas being regulated at an elevated pressure to form a slurry consisting essentially of a solid essentially all of which is ammonium tetrathiomolybdate containing a portion of the starting molybdenum and a mother liquor containing the balance of the molybdenum. The slurry is then cooled to ambient temperature and the solid is removed from the major portion of the mother liquor. The solid is then washed with water and with alcohol followed by removal of the resulting respective water and alcohol washes to remove the remaining portion of the mother liquor and soluble impurities from the solid. The resulting washed solid is then dried at ambient temperature to form the final ammonium tetrathiomolybdate.

摘要： A process is disclosed for applying a lubricant to a powdered material to control the fluidity of the powdered material. In the process one first obtains at least x number of samples of the powdered material without lubricant. Thereafter, increasing amounts of lubricant are applied to x-1 number of the samples. The bulk and tap densities of the samples are then measured and the Hausner ratio from the densities is calculated. The Hausner ratio versus the concentration of the lubricant in the powder samples is plotted and the concentrations of the minima lubricant in the powder samples at the point of the plot obtained in step e are determined. The concentration of lubricant determined in step f is applied to the remainder of the powdered material whereby an operational level of fluidity of the powder is achieved.

摘要： A method of forming a partial protective coating on phosphor particles to improve initial power output and maintenance of fluorescent lamps made with the phosphor. The phosphor particles are fluidized in a bed and at least partially enveloped by a coating precursor material. Residence time of the phosphor particles in the fluidized bed is short so that the phosphor particles are only partially coated with the coating precursor material. The coating precursor material is reacted to form a protective coating over at least a portion of the surface of the phosphor particles. The partially-coated phosphor particles are then annealed to cause the protective coating to selectively cover at least a portion of certain sites on the surface of the phosphor particles.
