Abstract
The crystal structure of the kaolinite mineral from Kalabsha, Aswan, Egypt, has been investigated with a two‐step procedure of the X‐ray powder pattern‐fitting. The unit cell is found to be triclinic, P1, a = 5.1577(15), b = 8.9417(23), c = 7.3967(40) Å, α = 91.672(5)°, β = 104.860(2) and γ = 89.898(2)°. The refinements of the non‐hydrogen atomic positions showed a reliability factors RWB = 0.037 and RB = 0.0417. The average rotation angle in the tetrahedral layer in 10°.
