The invention discloses a method for preparing gadolinium oxysulfide ceramic hollow microspheres. Additives are added in a water solvent and mixed uniformly to prepare a premixed liquid. , sintering aid; Gd 2 O 2 S slurry with a solid content of 75~85% is prepared by ball milling of Gd 2 O 2 S ceramic powder and premixed liquid, and then the initiator and catalyst are added and mixed evenly before use; A semi-circular arc-shaped super-hydrophobic track with a super-hydrophobic film, place the track on an inclined bench, and attach it with a heating tape below the track slope; use a dispenser needle so that the titration syringe is located 18-15cm above the track, and the Gd 2 The O 2 S ceramic slurry is injected into the titration syringe, and the inclined surface is controlled to be heated to 150~210 °C. The droplet size is controlled to be 0.18~1 mm by the intake pressure of the compressed air and the size of the pinhole. On the metal track coated with the superhydrophobic film, it is rolled down and heated to solidify into Gd 2 O 2 S microspheres . O 2 S ceramic hollow microspheres. |
