Description: Barium sulfate occurs naturally as barite ore or is produced synthetically through precipitation of barium salts with sulfuric acid. It serves as a high-density (4.5 g/cm³), chemically inert filler with exceptional X-ray opacity. Major applications include:
Medical: Radiocontrast agent (99.9% purity, USP grade)
Industrial: Drilling mud weighting agent (API 13A standard)
Plastics: Acid-resistant filler for PVC (improves density & sound damping)
Paints: Replacement for lead-based pigments
