Barytes By Deepak Micro Minerals

Barytes is naturally occurring barium sulphates with nodular particle structure in extra super snow white (ESSW) and off colour (Brown/Gray) and it is a fine free flow powder. It is insoluble in water and has low oil absorption this coupled with strong crystalline structure and high refractive index helps it to impart strength. Barites contain minimum 93 to 97% barium sulphate.
