    • A cerium based particle composition comprises: 50-90% by weight of cerium oxide, and at least 10% by weight of lanthanum oxide. The method to prepare the particle composition comprises: one or more water soluble salts of transition metal elements and/or alkaline metal elements are mixed with CeLaCl 3 solution; the mixed solution is precipitated with carbonate(s) and/or hydroxide(s) to obtain rare earth carbonate(s) doped by said one or more transition metal elements and/or alkaline metal elements; the carbonate(s) is calcined and crushed to obtain the said particle composition. The said composition can be mixed with water, optionally at the presence of additive(s), in order to obtain an abrasive for polishing glass for liquid crystal display and hard recording medium, particularly in the use of polishing glass substrate industry.
    • 铈基颗粒组合物包含:50-90重量%的氧化铈和至少10重量%的氧化镧。 制备颗粒组合物的方法包括:将一种或多种过渡金属元素和/或碱金属元素的水溶性盐与CeLaCl 3溶液混合; 所述混合溶液用碳酸盐和/或氢氧化物沉淀,以获得由所述一种或多种过渡金属元素和/或碱金属元素掺杂的稀土碳酸盐; 将碳酸钙煅烧并粉碎以获得所述颗粒组合物。 所述组合物可以任选地在添加剂的存在下与水混合,以获得用于液晶显示和硬记录介质的抛光玻璃的磨料,特别是在使用抛光玻璃基底工业中。
