Abstract: Using the wide angle x-rav scattering( WAXS ) and radial distribution function(RDF),the structure of pianlinitc occuring in China has been discussed.It is shown that pianlinitc is mainly composed of amorphous phase with less amount of order phase.The structural units constructing pianlinitc are tetrahedron[M04]( M=Si, Al)and octahetron[ AlO6 ](O=O,OH).The connecting of neighbour tctrahcdran with common vertex angle forms M-O lavcr( M=Al, Si),and the conncction of neighbour octahcdran with common edge or plane forms Al-0 layer. The structure of pianlinitc is formed from the such kind layers.Its structure change with temperatures is mainly caused by that of the correlation or order between structural units, and its structure in neighbour range is nearly unchanged.Pianlinitc is a clay rock with the structure different from that of the metakaolinites.
