Abstract

Combined electron micrographs and electron diffraction diagrams of single crystals of hydrated kaolins from Hongkong, North Carolina and Indiana show that they have tubular crystal form, but a structure different from that of halloy-site, or of kaolinite, being two-layer triclinic, with β=83°, α=91·8°. They differ in degree of crystallinity, and show some inter-layer water.
