摘要：

Studies were conducted on the production of silane modified kaolinite/silica core-shell nanoparticles (SMKS). The SMKS nanoparticles were prepared via the sol-gel technique using tetraethyl oxysilane (TEOS) as the precursor to form silica shells on the surface of kaolinite particles followed with silane treatment. TEM of the unmodified kaolin (ORK) and SMKS revealed that a layer of ultrafine silica particles were deposited on the kaolinite surface to form a new kind of core shell structure particles.
