Rare earth gradient doping transparent ceramic and preparation method thereof
The invention relates to rare earth gradient doped transparent ceramic and a preparation method thereof. The preparation method comprises the following steps: respectively preparing non-rare earth doped ceramic slurry and rare earth doped ceramic slurry; the two kinds of ceramic slurry are added into two feeding needle cylinders of a mixing device of the direct ink writing printer respectively, the on-line mixing technology and a feeding control program are combined, the feeding rate of the two kinds of slurry and the rotating speed of a mixing shaft in a mixing cavity are set and controlled, the two kinds of slurry are evenly mixed in the mixing cavity, the mixed slurry is extruded out of a discharging opening, and the mixed slurry is extruded out of a discharging opening. The feeding procedure and the mixing procedure are combined to realize continuous change of rare earth ion components in extruded slurry; obtaining a rare earth gradient doped transparent ceramic biscuit through a direct ink writing 3D printing process; and the rare earth gradient doping transparent ceramic biscuit is subjected to glue discharging, vacuum sintering, hot isostatic pressing sintering, annealing and polishing treatment, and the rare earth gradient doping transparent ceramic is obtained.
