Barium carbonate is widely used in the ceramics industry as an ingredient in
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 some claim that it can leach from glazes
into food and drink.
To provide a safe means of use, BaO is often used in fritted form.
In the brick, tile, earthenware and pottery industries barium carbonate is added to
clays to precipitate soluble salts (calcium sulfate and magnesium sulfate) that

Salts, basic, such as Barium carbonate, are generally soluble in water.
The resulting solutions contain moderate concentrations of hydroxide ions and
have pH's greater than 7.0. They react as bases to neutralize acids. These
neutralizations generate heat, but less or far less than is generated by
neutralization of the bases in reactivity group 10 (Bases) and the neutralization of
amines. They usually do not react as either oxidizing agents or reducing agents but
such behavior is not impossible.
(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.
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.
