Barium carbonate is a mineral carbonate known as Witherite and is the main source of barium salts. This chemical compound is widely used in the ceramic industry. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.
Physical and Chemical Properties:
Barium carbonate has the experimental formula BaCO3, which appears as a tasteless, odorless, and heavy white powder. Decomposes to BaO and CO2 at 1300 ° C. Its vapor pressure is low and almost insoluble in water, but soluble in alcohol, hydrochloric acid, and ammonium chloride; The most important physical and chemical properties of this compound can be summarized in the following table:
|Molecular Weight (g/mol)||197.34|
|Melting point (° C)||811|
|Boiling point (° C)||1,450|
|Chemical Structure Depiction|
Synthesis of Barium Carbonate:
For the commercial production of barium carbonate, the reaction of barium sulfide with sodium carbonate at a temperature of 60 to 70 ° C or the passage of carbon dioxide gas on barium sulfide at a temperature of 40 to 90 ° C is used. In this process, solid or dissolved sodium carbonate is added to barium sulfide, and barium carbonate is precipitated and smoothed.
BaS + Na2CO3→ BaCO3 + Na2S
BaS + H2O + CO2 → BaCO3 + H2S
Barium Carbonate Uses:
- Increased refractive index and luster in glass
- As a slurry in ceramic glaze
- In the manufacture of electroceramics
- Ahar adhesive stabilizer
- Coagulation of synthetic plastics
- Production of insecticides, germicides, and agricultural pesticides. like Hydrazine hydrate
- Melting agent in welding
- Making medical glasses
Barium Carbonate in the Production of Ceramic Tiles:
Barium carbonate is mostly used in ceramics (in ceramic glazes). This material acts as a slurry in the glaze as a crystallizing agent and combination with colored oxides produces unique colors that can not be obtained by other methods. Barium carbonate is added to clay in the manufacture of bricks, tiles, and pottery, converting soluble sulfates in the composition to insoluble barium sulfate. Soluble sulfates in pottery and ceramics absorb moisture from the air and expand, causing the ceramic to crack. Also, after the ceramics dry, the soluble sulfates in them appear as dandruff on the ceramics. Another application of barium carbonate is in the ceramic industry and the manufacture of electroceramics. These ceramics are made of iron oxide and carbonate along with barium or strontium and lead.
