The interaction between the talc layers is studied for a model system of two tetrahedral sheets. The upper sheet is a unit cell of tetrahedral sheet, [Si4010] 4- and the lower sheet an infinite hexagonal network of [Sio4] 4-. Using the electrostatic and Lennard-Jones equations, the energy for the interlayer interaction is calculated under the periodic boundary conditions. It is concluded that the interaction between the above two silicate sheets is attractive. The most stable configuration is predicted to be that the Si atom in the upper sheet is located nearly in the middle of the hexagonal hole in the lower sheet.
