PREPARATION METHOD FOR CERAMIC COMPOSITE MATERIAL, CERAMIC COMPOSITE MATERIAL, AND WAVELENGTH CONVERTER
A preparation method for a ceramic composite material, a ceramic composite material, and a wavelength converter. The preparation method comprises the steps of: respectively formulating an aluminium salt solution and fluorescent powders in a mass ratio of AlOto the fluorescent powders of (0.1-1):100; dispersing the fluorescent powders into a buffer solution having a pH 4.5-5.5 to obtain a suspension; performing titration of the suspension by means of the aluminium salt solution to obtain fluorescent powders coated by AlOhydrate film; calcining the fluorescent powders coated by AlOhydrate film to obtain fluorescent powders coated by AlO; mixing aluminium oxide powders with a particle size of 0.1µm-1 µm and aluminium oxide powders with a particle size of 1 µm-10 µm in a molar ratio of 100:(0.1-5) to obtain mixed aluminium oxide powders; mixing the fluorescent powders coated by AlOand the mixed aluminium oxide powders to obtain mixed powders, the fluorescent powders coated by AlObeing present in an amount of 40 % -90 % based on the weight of the mixed powders; and pre-pressing, and sintering the mixed powders to obtain the ceramic composite material.
