Barium Carbonate Used in Glazes As Crystallizing Agent

  barium carbonate is widely used in the ceramics industry as an ingredient in glazes. it acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means.

  its use is somewhat controversial since it can leach from glazes into food and drink. to reduce toxicity concerns, it is often substituted with strontium carbonate, which behaves in a similar way in glazes but is of lower toxicity.

  it is insoluble in water and soluble in most acids, with the exception of sulfuric acid.

Barium carbonate, chemical formula BaCO3, molecular weight 197.336. White powder. Insoluble in water, density 4.43g/cm3, melting point 881ºC. Decomposition at 1450 ° C releases carbon dioxide. Slightly soluble in water containing carbon dioxide, but also soluble in ammonium chloride solution to form a complex, to release carbon dioxide. Toxic. Used in electronics, instrumentation, metallurgy industry. Preparation of fireworks, the manufacture of signal shells, ceramic coatings, optical glass accessories. It is also used as a rodenticide, water clarifier and filler.
 

There are three crystal states: α, β and γ. The industrial product is white powder. Relative to Density4.43. α-type Melting_point1740ºC (90.9×103Pa), 928 ºC β-type into α-type, 811ºC γ-type into β-type. Almost insoluble in water, insoluble in alcohol, soluble in acid and ammonium chloride solution. At 1450ºC, it decomposes into BaCO3 and carbon dioxide. It decomposes with acid and reacts with sulfuric acid to form white barium sulfate precipitate. Slightly hygroscopic. Toxic.
