摘　　要：采用尿素作为中和剂,用液相沉积法制备了云母钛珠光颜料。采用扫描电镜和X射线衍射仪对珠光颜料进行表征,系统考察了pH值、温度、TiCl4浓度、加料速度、尿素加入量、搅拌速度、晶型促进剂、煅烧温度等制备参数对珠光颜料质量的影响规律,确定了珠光颜料的生产工艺参数,提出了将TiCl4部分转化成TiOSO4,分步加入尿素制备云母钛珠光颜料的新方法。The pearly pigment of mica titanium was prepared by using the liquid deposition method with the urea as precipitant. The composition and surface chemical characters of the pearly pigment of mica titanium were analyzed using XRD and SEM. The effect of the pH, reaction temperature, concentration of titanium salt, the joining speed, the joining amount of the urea, the stirring speed, crystal type promoting reagent, the calcining temperature and other parameters in the preparing procedure on the quality of pearly pigment of mica titanium was systemically studied. The technological parameters of industrial preparation for the pearly pigment of mica titanium were determined. A new preparation method was summarized which joined urea in batches and titanium salt which partly transformed from TiCl4 into TiOSO4.
