talc can be used as a lubricant, ground and used as a powder, it is also used in medicine in various forms and in scientific experimentation and helpful to use. In deodorants and in talcum powders. It mainly absorbs moisture thus preventing rashes (diaper or friction rashes). talc can be used as a lubricant, ground and used as a powder, it is also used in medicine in various forms and in scientific experimentation and helpful to use.

In nature talc does not exist in itsâ theoretical form or purity, but a small fraction of Mg and Si atoms can be replaced by iron (Fe), aluminium (Al) or nickel (Ni). Typically, the colour of talc stones is pale green or white, but the colour can vary from pinkish to dark green. The surface of talc stone has slippery feeling and pearly lustre. The unique fine structure of talc makes it ideal filler for protective coatings: Talcâs surface is electrically neutral, which makes talc highly hydrophobic, thus water.repellent. Talcâs particle form is platy, which is important for an optimum filler packing in the paint film. The platy particles also create a.good.barrier against
