摘要： A method of recovering a base phosphor from encapsulated phosphors, which comprises the steps of selecting a recovery vessel including a magnetic stir bar; adding to the recovery vessel, deionized water, a first batch of concentrated hydrochloric acid and encapsulated phosphor to form a stirred suspension; heating the stirred suspension to about 90° C. for about 2 hours; settling the stirred suspension; decanting the mother liquor and slurrying the remaining solids with a second batch of hydrochloric acid and water; decanting and washing the remaining solids with deionized water; filtering the remaining solids to form a filter cake; heating the filter cake at 110° C. in air for a time sufficient to form a dried filter cake; and screening the dried filter cake through a −325 mesh screen to yield a recovered base phosphor.

摘要： A phosphor particle has thereon a moisture resistant treatment of a metallic nitride. By moisture resistant is meant a condition allowing the phosphor particle to function in a humid atmosphere for a significantly longer period of time than an untreated particle. The method of making such phosphors comprises the steps of introducing an inert gas into a reaction vessel; charging phosphor particles into the reaction vessel; heating the reaction vessel to a reaction temperature; introducing a nitride coating precursor into the reaction vessel in a manner to avoid restrictive reactions; introducing a co-reactant into the reaction vessel; and maintaining the inert gas flow, co-reactant flow and precursor supply for a time sufficient to moisture-proof the phosphor particles. The nitride treated phosphor particles produced by this method, which can include the deposition of a nitride coating on the particles, have excellent efficacy ratings and strong luminance values in lamps after 100 hours use in high humidity (i.e., >95%). By avoiding restrictive reactions the method and apparatus can be used to manufacture commercial quantities of coated phosphors.

摘要： Fine particle size cobalt metal powder is prepared absent tailings by heating an aqueous solution of soluble cobaltic ammine halide to a temperature of at least about 120 degrees centigrade for a sufficient period of time to decompose said cobaltic ammine halide and form a cobalt containing precipitate. The precipitate is separated from the solution and reduced in a reducing atmosphere to produce fine metal cobalt powder.

摘要： Cobalt is recovered by treating aqueous solutions containing ammonia and cobalt ions with a sufficient amount of an acid in the presence of a catalyst to convert the cobalt ions to a cobalt hexammine ion which is precipitated and separated from the resulting solution. According to another aspect of the invention, a cobalt compound is precipitated from an aqueous solution of cobaltic hexammine halide by treating the solution with a metallic hydroxide and the precipitate is subsequently reduced to form fine cobalt powder.

摘要： A phosphor composition consisting essentially of particles of zinc sulfide electroluminescent phosphor activated with from about 0.7% by weight of about 1.3% by weight of manganese, based upon the total weight of the phosphor composition, wherein the electroluminescent emission of the phosphor has an x color coordinate value of from about 0.522 to about 0.532 and a y color coordinate value of from about 0.460 to about 0.470 and an efficiency of greater than about 5.6 lumens per watt at 115V/400 Hz. A solid state process for producing the foregoing phosphor comprises a multiple firing in order to incorporate manganese, chloride and copper ions into the zinc sulfide lattice. Controlled levels of manganese yield highly efficient electroluminescent phosphors.
