Alternative title: Hydrothermal synthesis of high-purity layered clay minerals

Description:

The hydrothermal method can be used to synthesize high purity layered clay minerals. Experiential techniques for the hydrothermal synthesis of layered clay minerals are described. The method of cleaning, annealing and welding Au capsule in the hydrothermal experiment is also presented. Two types of starting materials: quenched glass and dried gel, were prepared through chemical selection, pretreatment, mixing, and thermal treatment. The starting materials have different chemical compositions of smectite with different layer charge and interlayer cations, and those in smectite-mica pseudobinary system. The synthesized minerals were tabulated with starting material composition, synthesis temperature, and reaction time. The procedure and product list would be useful for clay mineralogy and materials science, especially for materials informatics.
