【摘要】 设计将微乳体系既作为制备纳米粒子的反应介质 ,又作为云母的表面改性体系 ,进行了云母钛珠光颜料的制备研究。XRD和SEM分析结果表明 ,所制产品为 10～ 3 0nm的二氧化钛粒子呈球形均匀包覆于云母基质表面 ,EDS的测定结果表明 ,TiO2 的包覆率约为2 1 9%。更多还原

【Abstract】 Microemulsion system was designed not only as reaction medium for preparation of nano particles,but also as surface modifying system for the muscovite powder,a new process was studied to prepare-mica titania pearlescent pigment.The results of XRD and SEM showed that TiO 2 with size of 10～30 nm and shape of sphericity is coated on the surface of muscovite base evenly, and its coating rate is about 21 9%.更多还原
