| 摘 要： | 除去高岭土中铁、钛等杂质，有利于它的广泛应用．对淮北地区高岭土进行电化学处理，并对处理前后的试样进行了SiO2，Al2O3，Fe2O3和TiO2含量的测定，发现在保持SiO2和Al2O3总量基本不变的前提下，Fe2O3，TiO2的脱除率分别达到60．0％和31．7％．同时配合透射电子显微镜、X-衍射和EDX能谱对样品进行分析．结果表明，电化学处理后的高岭土颗粒明显细化，铁、钛含量明显减少．

| Abstract: | Low-grade kaolin contains iron and titaniumimpurities,which restrain its wide application.Kaolin from Huaibei,processed by electrochemistry,has been analyzed,and comparingwith unelectrolyzedkaolin byX-rays and transmission electron microscope(TEM),the results show that the removal efficiencies of Fe_(2)O_(3)and TiO_(2) are 60.0% and 31.7%,respectively.Meanwhile the contents of SiO_(2 )and Al_(2)O_(3)do not decrease.The sizes of electrolyzed kaolin andcontents of iron and titanium wereobviously reduced. |
