Abstract

The invention discloses a yttrium oxide laser transparent ceramic material with incentive elements in continuous gradient distribution and a preparation method thereof, wherein a host material is Y2O3; and the incentive elements RE are Yb, Tm or Nd. The yttrium oxide laser transparent ceramic material is characterized in that the concentration of the incentive elements RE in the host material is in a continuous gradient distribution along the axial direction of the host material. The preparation method comprises the steps of (1) preparing Y(NO3)3 solution, RE(NO3)3 solution and urea solution; (2) preparing RE:Y2O3 spherical nano-powder; (3) preparing Y2O3 spherical nano-powder; (4) mixing the Y2O3 spherical nano-powder and the RE:Y2O3 spherical nano-powder which are the same in particle size to prepare mixed powder; ball-milling, dispersing and ultrasonically dispersing to obtain slurry with high suspending stability; (5) centrifugally separating and removing a liquid phase, and drying to obtain a gradient blank; and (6) sintering in vacuum after biscuiting, and finally annealing. By adopting the preparation technology of a common ceramic material, the preparation method is simple in process, low in cost and suitable for large-scale production.
