The effects of several-hundred-hour mechanical-mortar dry grinding of kibushi-clay which is a kaolin mineral of fireclay type were studied by x-ray diffraction, thermal, electron microscopic and other methods and compared with those of kaolinite.
Kaolin kaolin is also called kaolinite. kaolinite is a clay mineral, part of industrial minerals, with the chemical composition al 2 si 2 o 5 oh 4.it is a layered silicate mineral, with one tetrahedral sheet linked through oxygen atoms to one octahedral sheet of alumina octahedra.
In an attempt to clarify possible mechanisms for producing such kaolinite samples, we have used powder x-ray diffraction to study the effects of mechanical grinding on the nature of layer stacking in the 40 m fraction of the american petroleum institute kaolinite standard no. 9 from mesa alta, new mexico.
