  • Effect of Crystallisation Time on the Synthesis of Zeolite Y from

    Abstract. In this study, the effect of crystallization time on the synthesis of zeolite Y from Elefun kaolinite clay was investigated. During the synthesis of zeolite Y, the raw Elefun kaolinite clay was beneficiated thoroughly with water for 7 days before it was calcined at a 850oC for 6 hours to thermally convert it to metakaolin.
