Place of Origin:
CAS NO 513-77-9 BaCO3 Barium carbonate was an important material for building material UN NO 1465
Barium carbonate is a white powder. Barium carbonate is insoluble
in water and soluble in most acids, with the exception of sulfuric acid. Barium
carbonate has a specific gravity of 4.275. Barium carbonate is toxic by ingestion.
There have three different powder as below :
• Barium carbonate standard powder is used in the production of special
glass, glazes, brick and tile industry, ceramic and ferrite industry, also used for
removing of sulfates in phosphoric acid production and chlorine alkali electrolysis
• Barium carbonate fine powder is specially developed for usage in the brick
and tile industry and for the removing of sulfates.Other applications are in the
ceramic and ferrite industry. It is also used in the production of chlorine alkali
electrolysis and for the purification of phosphoric and tartaric acid.
• Barium carbonate granular is used for the production of display glass,
crystal glass and other special glass, glazes, frits and enamels, also used in the

Barium carbonate is made from barium sulfide soln by one of two methods.
In the first, the soda ash method, the barium sulfide soln is treated with sodium
carbonate, either dissolved or in solid form, producing barium carbonate and
sodium disulfide.The usual operating temp is 60-70 deg C. The resulting slurry is
filtered and the barium carbonate is washed, dried, ground, and packaged. This
process is thought to be used by about half of the industry .
In the second main method, carbon dioxide gas is passed through a barium sulfide
soln, either batchwise or on a continuous basis, at 40-90 deg C. Temp and other
operating conditions have a pronounced effect on the size and characteristics of the
particles formed. To obtain a satisfactory product, the barium sulfide must react with
slightly less than the stoichiometric amt of carbon dioxide; the carbon dioxide may
be supplied in pure form, or may be obtained from the combustion gases of barium
sulfide reduction kilns.
Barium carbonate was mainly used in ceramic glazes,glass making ,bricks
Rapid oral administration of a soluble sulfate in water, such as magnesium or
sodium sulfate (2 oz), alum (4 gm), or very dilute sulfuric acid (30 ml of a 10%
solution diluted to 1 qt). These agents precipitate barium as the insoluble sulfate.
Gastric lavage or induced emesis. Seek medical attention.
Air & Water Reactions
It is insoluble in water and soluble in most acids, with the exception of sulfuric acid.
Non-combustible, substance itself does not burn but may decompose upon
heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite
combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve
flammable hydrogen gas. Containers may explode when heated. For electric
vehicles or equipment, lithium ion batteries or sodium batteries should also be
(INGESTION ONLY): excessive salivation, vomiting, severe abdominal pain, and
violent purging with watery and bloody stools; a slow and often irregular pulse and
a transient elevation in arterial blood pressure; tinnitus, giddiness and vertigo;
muscle twitchings, progressing to convulsions and/or paralysis; dilated pupils with
impaired accommodation; confusion and increasing somnolence, without coma;
collapse and death from respiratory failure and cardiac arrest.
