Centrifugal forming method for preparing transparent ceramic laser bar
The invention provides a centrifugal forming method for preparing a transparent ceramic laser bar in order to solve the problems in the existing transparent ceramic preparation technique, belonging to the field of an optical transparent ceramic material preparation technique. The method comprises the following steps: mixing Al2O3, Y2O3 and Yb2O3 powders according to the chemical proportioning of (Y[1-x]Ybx)3Al5O12 (0.01<=x<=0.1), preparing a raw material powder by a solid-phase process, mixing the transparent ceramic powder with a dispersing agent and deionized water to prepare a slurry, and carrying out centrifugal forming to obtain a bar-shaped billet; and sufficiently drying the billet, carrying out vacuum sintering at 1700 DEG C for 5-10 hours, and carrying out heat treatment and sanding polishing to obtain the transparent ceramic laser bar. The laser bar obtained by the centrifugal forming method has the advantages of low porosity, favorable uniformity and high density; and the transmittance can reach 70% above within the visible light range, thereby overcoming the defects of nonuniform density distribution, long forming cycle, high porosity and the like in other dry processes and wet processes for forming. The transparent ceramic laser bar can be used as a solid laser operation material, and has favorable application prospects in the field of optical transparent ceramics.
