Obtaining Highly Crystalline Barium Sulphate Nanoparticles ...

Baryte is a sulfate of barium with chemical formula BaSO 4. It is generally white or colorless, chemically inert, insoluble in water, with high density, and the main source of barium. Although baryte contains a “heavy” metal (barium), it is not considered to be a toxic chemical reagent by most governments because of its extreme insolubility .
