Patent ID: 7303699

Claim:
Method for producing a high-density, translucent scintillator ceramic, the method comprising: doping a metal oxysulfide (MOS) with specific rare earth elements (Ln), wherein the metal oxysulfide (MOS) has the generic formula (I) (M 1-x Ln x ) 2 O 2 S Formula (I) wet milling a powder of the doped metal oxysulfide with the addition of an organic milling fluid until a particle size of the powder is <10 μm, wherein the powder has a specific surface area of 10 m 2 /g; producing a powder body from the powder, wherein the powder body has a green density selected from the range 40% to 60% inclusive; and pressurelessly sintering the powder body obtained is in vacuum or in an inert gas atmosphere at a sinter temperature between 1200 to 1450° C. inclusive.
