Talc Mineral | Physical - Optical Properties, Occurrence, Uses

5/3/2019· Talc is easily distinguishable by its extreme softness, color is white, colorless, pale to dark green, or yellowish to brown. Crystals are rare; it is most commonly found in foliated, fibrous, or massive aggregates. It is often found mixed with other minerals, such as serpentine and calcite. Dense, high-purity talc is called steatite.

In this work, we modelled the structure, the compressional behaviour and the physical properties of talc over a wide range of pressure using a quantum mechanical approach based on periodic boundary conditions. We adopted the density functional theory using the B3LYP-D* functional, which includes a correction for the dispersive forces and all-electron Gaussian-type orbitals basis sets. An ...
