Title: Method of processing phosphors
IPC: B03D1/02
Filed: 1965-08-24
Abstract: A process for washing and classifying a phosphor, for example alkaline earth halophosphates such as calcium chlorofluorophosphate activated by antimony and manganese and prepared by a firing process, comprises forming a dispersed slurry of the phosphor in an aqueous solution of a washing agent and a chelating agent e.g. ammonia solution of ethylenediamine tetra-acetic acid (E.D.T.A.) or nitrilotriacetic acid or hydroxy-E.D.T.A.; passing the slurry into an elutriation column where the upward velocity of the liquid in the column is maintained at such a value that phosphor particles greater than a predetermined maximum particle size e.g. 20m  drop downwards in the column; and recovering a washed phosphor having a particle size less than the predetermined maximum particle size.  The chelating agent prevents agglomeration of the particles during the sizing.  The sized particles may then be dried, mixed with a solvent, and the mixture passed through a sieve to deagglomerate outsize particles formed during the drying.  In the preparation of a coating suspension to be applied to a glass surface, dried phosphor is fed into a solution of xylol, 2-butyl alcohol, "Armeen CD", (R.T.M.) (a mixture of primary amines having alkyl radicals containing from 12 to 18 carbon atoms), the phosphor settled for 24 hours, separated, and resuspended in "Armeen CD", sufficient ethylcellulose lacquer being added to form a phosphor suspension for fluorescent tubes for lamps for instance.
