SrSO4
ceramicStrontium sulfate (SrSO₄) is an inorganic ceramic compound that occurs naturally as the mineral celestine and is also manufactured synthetically for industrial applications. It is valued in industries requiring high-density, chemically stable particulates and is commonly used as a weighting agent in oil and gas drilling fluids, a radiopaque filler in medical imaging formulations, and a pigment or filler in paints, coatings, and plastics. Engineers select SrSO₄ over alternatives when chemical inertness, high specific gravity, and low solubility in aqueous environments are critical—making it particularly suited to demanding downhole and subsurface applications where corrosion resistance and dimensional stability matter.
