03,PATENTANSPRÜCHE : 1. Verfahren zur Herstellung von als Sensibilisator Sb3+ und gegebenenfalls Mn2+ enthaltenden lumineszenten Stoffen des Apatittyps (Calciumhalophosphate) durch Vermischen der erforderlichen Ausgangsstoffe, Glühen des erhaltenen Gemisches in einem geschlossenen Quarztiegel, Zerkleinern des geglühten EMI2.1 Tunnelofen, in einer im Gegenstrom zu den Tiegeln geführten sauerstoffhältigen Atmosphäre bei einer Temperatur von etwa 12000C vorgenommen und das Mahlprodukt mit Säure gewaschen wird. EMI2.2 03, PATENT CLAIMS: 1. Process for the production of luminescent substances of the apatite type (calcium halophosphates) containing Sb3 + and optionally Mn2 + as a sensitizer by mixing the required starting materials, calcining the mixture obtained in a closed quartz crucible, crushing the calcined EMI2.1 Tunnel furnace, carried out in an oxygen-containing atmosphere led in countercurrent to the crucibles at a temperature of about 12000C and the milled product is washed with acid.
