摘要： Provided is a method for recovering an abrasive material component from used slurry having cerium oxide as the principle component of the abrasive material therein, the abrasive component recovery method being one in which post-recovery treatment of the abrasive agent and waste liquid is easy. Also provided is cerium oxide recovered through the novel recovery method. A method for recovering an abrasive material component from used abrasive slurry containing cerium oxide in the abrasive material thereof is characterized in that the abrasive material component is recovered by: adding a magnesium salt to the used abrasive slurry; coagulating the abrasive material component and causing the sale to sediment from the abrasive slurry, which contains the abrasive material component and components derived from the material subjected to abrasion; and separating the solids and liquids.
摘要翻译：提供了一种用于从其中具有氧化铈作为研磨材料的主要成分的废浆中回收研磨材料成分的方法，磨料成分回收法是研磨剂和废液的回复后处理容易的方法。还提供了通过新的回收方法回收的氧化铈。从磨料中含有二氧化铈的研磨浆料中回收研磨材料成分的方法的特征在于：通过以下步骤回收研磨材料成分：向所用磨料浆中加入镁盐; 使研磨材料组分凝结并使磨料从沉积物中沉淀出，磨料浆料含有研磨材料组分和衍生自经受磨损的材料的组分; 并分离固体和液体。

摘要： Provided are fine abrasive particles which have a high rate of polishing and generate few polishing flaws. A process for producing then abrasive particles is also provided in which the fine abrasive particles have a reduced coefficient of fluctuation in particle diameter, the production steps are simple, and the production cost is low. The fine abrasive particles comprise cerium oxide, at least one element selected from La, Pr, Nd, Sm, and Eu, and one or more element selected from Y, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, and are characterized in that the cerium oxide has a Ce content of 20 mol % or higher and that the sum (mol %) of the content of the at least one element selected from La, Pr, Nd, Sm, Nd Eu and the content of Ce in the cerium oxide is greater than the sum (mol %) of the contents of the one or more elements selected from Y, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu.
