Barium Sulfate Uses You Should Know

Barium sulfate is a white crystalline solid used widely across multiple industries due to its excellent chemical stability and high density. It's known for being insoluble in water and resistant to heat and acid. In industrial applications, barium sulfate is a key ingredient in coatings, plastics, rubber, and even X-ray imaging for medical purposes. It is odorless, safe to handle when used correctly, and a valuable component in chemical processes, especially in producing other barium compounds.

Types of Barium Sulfate in Use 

The types of barium sulfate available vary based on purity and intended use. There are natural and synthetic types. Natural types of barium sulfate (barite) are mined and used mostly in drilling muds, while synthetic grades are refined for pharmaceutical and chemical applications. High-purity forms are also favored in the cosmetics and coatings industries. Each type serves a specific purpose, from filler material in paints and plastics to specialized uses in radiology and medical diagnostics.

BaSO₄ and Its Role in Modern Chemistry 

BaSO₄, the chemical formula for barium sulfate, represents its precise molecular structure: one barium ion combined with a sulfate ion. Its density and opacity make BaSO₄ particularly useful in medical imaging, especially for gastrointestinal X-rays. It’s also a component in brake linings, battery pastes, and pigments. This compound doesn’t react with most chemicals, making it reliable in harsh environments. The chemical identity of BaSO₄ makes it essential for safe and stable industrial reactions.

CAS Number 7727-43-7: What It Means 

The unique identifier 7727-43-7 corresponds to barium sulfate in the Chemical Abstracts Service (CAS) registry. This number is used internationally to specify chemical substances in research, safety protocols, and global trade. When buying or handling barium sulfate, referring to 7727-43-7 ensures product consistency and regulatory compliance. Whether you’re ordering for lab work or bulk industrial use, this identifier confirms the material’s exact chemical identity.
