    • PURPOSE: An HCl-treatment method of ceramic raw materials such as kaoline and cericite is provided, which eliminates CaO and other impurities effectively by adjusting pH of raw materials, and distributes particle size. Accordingly, the method shortens process and produces raw materials on a large scale. CONSTITUTION: The method comprises the steps of: ball-milling 1kg of kaolin and cericite clay, and 1.5kg of water for 24hrs.; dispersing with Na2SiO2; adding HCl to be pH9-10 and standing; separating the lower part(CaO, Fe2O3, etc.) with the upper part(solution); adding HCl to adjust the solution between 2-4; settling for 6hrs or longer, resulting in particle size distribution(2-5micrometer); filtering.
    • 目的:提供高岭土和铈锰等陶瓷原料的HCl处理方法,通过调整原料的pH值,分散粒度,有效消除了CaO等杂质。 因此,该方法缩短了工序,大量生产原料。 方法:该方法包括以下步骤:将1kg高岭土和硅灰土和1.5kg水球磨球24小时。 用Na2SiO2分散; 加入HCl至pH9-10并静置; 用上部(溶液)分离下部(CaO,Fe2O3等); 加入HCl调节溶液2-4; 沉降6小时或更长,导致粒度分布(2-5微米); 过滤。
