    摘要： PROBLEM TO BE SOLVED: To provide a cerium oxide powder, a method for producing the same, and a dispersion liquid containing the powder.
    SOLUTION: The cerium oxide powder has a BET surface area of 25-150 m
    2 /g and contains primary particles having an average diameter of 5-50 nm. The layer close to the surface of each primary particle has a depth of about 5 nm, and the carbonate concentration in the layer close to the surface is decreased toward inside from the surface. The content of carbon deriving from carbonate groups is 5-50% by area percentage on the surface and 0-30% by area percentage at a depth of about 5 nm in the layer close to the surface. The content of cerium oxide is at least 99.5 mass% based on powder. Further, the content of carbon is 0.01-0.3 mass% based on powder. The dispersion liquid is sufficiently stable even when an additive is not added additionally and can be used for chemical and mechanical polishing within a range from neutrality to weak alkalinity.

    摘要： PROBLEM TO BE SOLVED: To provide a process with which a mixture composed of an organosilicon compound and a solid can simply and inexpensively be post-treated. SOLUTION: The process for preparing the organosilicon compound represented by general formula (I): (R 1 R 2 R 3 SiR 4 ) 2 S x is carried out as follows. A halogenated alkoxysilane represented by general formula (II): R 1 R 2 R 3 SiR 4 X is reacted with an anhydrous polysulfide represented by general formula (III): M 2 S z and/or an anhydrous sulfide represented by general formula (IV): M 2 S and, as necessary, sulfur in an organic solvent. In the method, the organic solvent is separated from the resultant suspension and the obtained mixture containing the organosilicon compound represented by general formula (I) and a solid MX is then mixed with water containing at least one buffer to separate the formed phase.
