Mechanism and structure analysis of SiO2-coated CaCO3 superfine particles(SiO2包覆超细CaCO3的结构和机理分析)
合成了表面包覆SiO2的超细CaCO3。通过XPS,RD对包覆表面层结构的分析,证实了SiO2以无定形包覆于CaCO3表面,并在其表面形成了Si-O-Ca键。对SiO2包覆超细CaCO3的机理分析结果可知:Na2SiO3的加入量是影响包覆效率的重要因素,由于硅酸易自聚,控制SiO2与CaCO3的重量比约为4%～5%时为包覆的最佳点;CaCO3晶粒度大小影响分散性能,进而影响包覆效率,分散性能好的包覆效率较高。...
