Description
Barium Carbonate Product Overview
Barium carbonate (BaCO3) is a white, fine powder that is practically insoluble in water. However, it dissolves in stomach acid and other acids, which releases toxic barium ions, so, unlike inert Barium sulfate, it is toxic if swallowed.
In addition, ceramic producers use it in glazes, where it creates matte surfaces and improves color, and brick and tile producers add it to clay to prevent white sulfate scum on fired products. Similarly, glass producers use it in specialty and optical glasses, while magnet producers use it as the barium source for barium ferrite permanent magnets. It also serves as the starting material for other barium compounds, such as Barium chloride.
Because of its toxicity, Zyntex supplies barium carbonate only for professional industrial use. Related compounds in our range also include Strontium Titanate and Barium Metaborate.

⚠️ Safety & Handling: Harmful if swallowed, because stomach acid dissolves it and releases toxic barium. For professional use only, so avoid dust formation and ingestion, and also wear gloves, eye protection and dust protection. Store in tightly closed containers away from acids and food. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
Why is barium carbonate toxic while barium sulfate is not?
Barium carbonate dissolves in stomach acid and releases barium ions, whereas barium sulfate remains insoluble even in acid.
Why is it added to bricks?
Because it reacts with soluble sulfates in clay, it prevents white sulfate scum on the surface of fired bricks and tiles.
