【Abstract】 A new method-molten glass crystallization method(MGCM)for the preparation of the YAG single crystal powder is introduced.The effect of various processing parameters on the crystallization phase is analyzed by X-Ray diffraction(XRD).It is found that the optimum crystallization temperature is 1100℃.In the molten glass,the most suitable Al2O3content is 10.71wt%;the proper mass ratio of PbO to SiO2is 3.86.In addition,adding seed crystals can effectively inhibit the formation of the impurity phase and improve the yield of YAG single crystal powder.更多还原
