柳永《望海潮》摘要：Aluminum from AlO - tetrahedra of as-synthesized zeolites is extracted and substituted with silicon to form zeolite compositions having higher SiO/AlO molar ratios and exhibiting distinctive chemical and physical properties. The preparative procedure involves contact of the starting zeolite with an aqueous solution of a fluorosilicate salt using controlled proportions and temperature and pH conditions which avoid aluminum extraction without silicon substitution.
