| Abstract: | Zeolite 4A for builder was synthesized by the method of adding aluminum compound to the natural kaoloine from Chaoyang area, which contained SiO 2 55.5%, Al 2O 3 30.4%. The crystal product was characterized by X ray diffraction to the powder. The effects of component ratio of original reactant mixture, temperature and period of crystallization on the pro duct quality were investigated, respectively. The final products have high Ca exchang capacity of 298.8mg CaCO 3/g. |
