摘要： Disclosed is a method of producing high-purity lithium carbonate and barium sulfate from discarded lithium secondary batteries, including: a first process for producing high-purity lithium phosphate from a discarded battery; and a second process for producing lithium sulfate from the lithium phosphate and producing lithium carbonate and barium sulfate from the lithium sulfate. The second process has steps of (a) producing a liquid mixture of lithium phosphate and sulfuric acid, (b) obtaining lithium sulfate by condensing the liquid mixture, (c) dissolving the lithium sulfate in water or a sodium hydroxide aqueous solution, depositing phosphoric acid as lithium phosphate, and performing solid-liquid separation (d) depositing lithium carbonate and performing solid-liquid separation to obtain lithium carbonate, (e) finely grinding the lithium carbonate and classifying the particles, (f) controlling a particle size and shape by dissloving edges of particles or minute particles, (g) performing solid-liquid separation, and (h) depositing barium sulfate.

摘要： A method and apparatus for continuous fabrication of homogeneous thin flake or powder electrolyte material from inorganic salt, metallic or similar materials or from mixtures of such materials for use in Carbonate Fuel Cell (nullCFCnull) power plants. Electrolyte precursor powders are fed to a continuous blender type mixer using precision metering equipment that controls material feed rates. The homogenous mixture of blended powders is then fed into a high temperature melting tank in which the mixture is melted, forming the desired molten eutectic composition. The liquid eutectic melt drips from the melting tank through ceramic or metallic nozzles and splat-cools on a rotating, water-cooled metal cylinder to produce uniform size, thin flake material. The thin flake electrolyte material can be used as-is, or it may be further processed using continuous grinding and powder fabrication equipment.

摘要： A sodium bicarbonate product comprises particles containing sodium bicarbonate and an organic material that is a solid at ambient temperature. The particles have a structure comprised of individual crystallites of sodium bicarbonate attached together in the particle. More than 95% by volume of the particles have a size less than 200 μm. Particles of the product are hollow and are formed of an outer shell of the crystallites. The product may be used, for example, as a leavening agent in the production of cooked foods. The product may be produced by spray drying a solution or slurry dissolved organic material and dissolved sodium bicarbonate. The sodium bicarbonate may be present as a suspension.
