Abstract

A rapid and simple test to distinguish halloysite from kaolinite in mineral mixtures has been developed based on differences in the rate and extent of formamide intercalation. The results of quantitative analysis by formamide intercalation reaction GEC contained 90% of kaolin minerals, GEC contained of 86% of halloysite and GYK contained of 59% kaolinite. The extent of formamide intercalation by kaolinite was likely influenced by sample crystallinity.
