Kaolin is destroyed due to dehydration, forming a poorly crystallized transition phase - Metakaolin.Because the molecular
arrangement of metakaolin is irregular, it shows thermodynamic metastable state and has gelling property under proper
excitation.Metakaolin is a kind of highly active mineral admixture, which is amorphous aluminum silicate formed by low temperature calcination of ultrafine kaolin and has high pozzolanic activity.Kaolin is easily dispersed and suspended in water, has good plasticity and high cohesiveness, excellent electrical insulation properties, and has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, kaolin is suitable for ceramics, rubber, building materials and other industrial fields.
