摘　　要：研究了铅铬黄粒子的微胶囊化及其机理；探讨了对粒子表面形貌的量化表征方法．结果表明，在油包水（Ｗ／Ｏ）乳液中对铅铬黄粒子进行无机微胶囊化是一提高其耐酸、碱性的有效方法．颜料粒子的表面形貌可用其表面分形维数（Ｄ）量化表征．Microencapsulation of lead chrome yellow and its mechanism have been researched and the quantitative method characterization of particle surface shape by surface fractal dimensionality( D ) has been investigated. The results showed that inorganic microencapsulation of the lead chrome yellow particles in W/O emulsion is an effective method, raising the acid/baseresistance of the particles.
