    摘要: The invention provides a process for the production of zeolite A from kaolin by conversion of the kaolin into meta-kaolin followed by reaction of the meta-kaolin in an aqueous alkaline medium, wherein the conversion of the kaolin into the meta-kaolin is conducted at temperatures of between 700.degree. and 950.degree. C. in the presence of alkaline earth compounds and optionally in the presence of uncolored halides and/or halogens, wherein the process may be conducted under reducing conditions and in the presence of alkali metal compounds.
