本发明是关于对卤粉单个粒子形状和粒径分布(应理解为轴径分布译注)的改进。按传统方法生产的卤粉,单个粒子呈四角柱状体,表面凹凸不平,对可见光的透过性不好,用这种卤粉制造荧光灯时,在焙烤过程中亮度显著下降。本发明克服了由于焙烤而引起荧光粉亮降低的缺点,改善了烤焙特性,而且提供烧 The present invention relates to improvements in the shape and particle size distribution of individual particles of a halogen powder, which should be understood as a distribution of shaft diameters. According to the traditional method of producing the halogen powder, the single particles are in the form of a square columnar body, the surface is uneven and the permeability to the visible light is not good. When the fluorescent lamp is manufactured from the halogen powder, the brightness decreases obviously during the baking process. The present invention overcomes the drawbacks of reduced fluorescent powder due to baking, improved baking characteristics, and provides burn
