Buying Guide: Barium Carbonate 99.2% Min
If Barium Carbonate 99.2% min is a critical raw material for your operations—especially in ceramics, glass production, brick manufacturing, or chemical processing—this comprehensive guide will assist you in making an informed and technically sound purchasing decision.
Description
Barium Carbonate (BaCO₃) is a white, odorless inorganic compound primarily derived from barite or witherite through chemical synthesis or purification processes. It appears as a fine white powder and is insoluble in water but soluble in acids, making it highly suitable for chemical reactions and industrial applications. With a purity of 99.2% minimum, this grade of Barium Carbonate meets strict industrial specifications for high-performance uses.
This chemical is predominantly applied in ceramics, frit glazing, bricks, glassmaking, pigments, and precipitation of sulfates in chemical industries.

Main Applications
1. Ceramic Industry
Used to prevent scumming in tiles and bricks by precipitating soluble salts. Barium Carbonate reacts with sulfates in clay to form insoluble Barium Sulfate, improving final product durability.
2. Glass Manufacturing
Acts as a flux to reduce melting temperatures and improves clarity and refractive index in certain specialty glass applications.
3. Brick & Tile Production
Helps neutralize soluble salts like magnesium and calcium sulfate, preventing white efflorescence and structural flaws in bricks.
4. Chemical Industry
Used in the manufacture of Barium salts such as Barium Nitrate, Barium Chloride, and Barium Hydroxide, often for fireworks, pigments, and other specialty chemicals.
5. Electronics & Ferrites
Involved in producing ferrites used in electronic devices. It stabilizes ceramic dielectric properties in capacitors and other components.
6. Water Treatment
Reactively removes sulfates and other undesirable ions from industrial waste streams by precipitation.

Is Barium Carbonate Toxic?
Yes, Barium Carbonate is toxic if ingested or inhaled due to the soluble Barium ions it releases under acidic conditions. Proper precautions must be taken during handling:
-
Use PPE: gloves, dust mask, goggles
-
Follow MSDS and local environmental and safety guidelines
-
Never use in food-contact materials
Despite its toxicity, it is safe for industrial and commercial use under controlled conditions.
Is Barium Carbonate Explosive or Reactive?
-
Non-explosive under standard handling conditions
-
Should be stored away from acids (which release toxic Barium ions)
-
Incompatible with strong oxidizers and mineral acids
-
Store in cool, dry, and ventilated areas
