Crystal structure of talc
Talc is a trioctahedral layered mineral; its structure is similar to pyrophyllite, but with magnesium in the octahedral sites of the composite layers. The crystal structure of talc is described as TOT , meaning that it is composed of parallel TOT layers weakly bonded to each other by weak van der Waals forces .
