| titleOfInvention | Agglomeration of phosphor materials prior to calcination to eliminate calcining in receptacles |
| abstract | THERMALLY REFINED PHOSPHOR MATERIAL, SUCH AS ALKALINE EARTH HALOAPATITE PHOSPHOR MATERIAL, IN THE FORM OF FINELY DIVIDED PARTICLES MAY BE PRODUCED ON A CONTINUOUS BASIS IN A FURNACE, WITHOUT STICKING OF PHOSPHOR MATERIAL TO THE FURNACE WALLS AND WITHOUT SIGNIFICANT LOSS BY VOLATILIZATION OF ACTIVATOR ELEMENTS, BY INITIALLY FORMING PARTICLES OF PRECURSOR PHOSPHOR MATERIAL CAPABLE OF PRODUCING THE DESIRED PHOSPHOR MATERIAL INTO COHERENT BUT STILL FRIABLE BODIES. THE COMPACTED BODIES ARE THEN CONTINUOUSLY FED TO A FURNACE, SUCH AS AN INCLINED TUBULAR FURNACE, WHERE THEY ARE HEATED TO INCANDESCENCE TO FORM AND/OR THERMALLY REFINE THE PHOSPHOR MATERIAL. THE COMPACTED, THERMALLY REFINED BODIES OF ACTIVATED PHOSPHORS EMANATING FROM THE FURNACE ARE EASILY CRUSHED OR ROLLED TO YIELD ACTIVATED PHOSPHOR GRANULES IN THEIR ORIGINAL PARTICULATE FORM READY FOR USE IN FLUORESCENT LAMP COATINGS AND THE LIKE. |
