    摘要: CALCIUM METAL SILICATE AND ZINC ORTHOSILICATE PHOSPHORS ARE PRODUCED USING A CONTINUOUS HOMOGENEOUS PRECIPITATION TECHNIQUE. PRECIPITATION OF A REACTIVE HYDROUS OXIDE INTERMEDIATE UNDER INTENSIVE MIXING CONDITIONS, FOLLOWED BY SPRAY DRYING, WASHING, DRYING AND CALCINATION YIELDS THE DESIRED FLUORESCENT MATERIAL.
