- Barium carbonate
(BaCO3), also known as witherite.
- Witherite
crystallizes in the orthorhombic system. The crystals are invariably
twinned together in groups of three, giving rise to
pseudo-hexagonal
forms somewhat resembling bipyramidal crystals of quartz, the faces are
usually rough and striated horizontally.
- Barium carbonate
powder is dense and white and is manufactured either from the mineral
barite (BaSO4) or from barium chloride.
- Subsequently a
precipitation process is used to get the carbonate form. There are
several crystalline forms of BaCO3, alpha is the most stable.
- Barium is a dense
alkaline earth metal that occurs naturally in ore deposits and makes up
0.05% of the Earth's crust. Barium and its
compounds may be found in
nature or produced industrially for various uses.
- Barium carbonate
produces gases as it decomposes and these can sometimes cause many
pinholes or blisters in glazes. There are many
barium frits
available and incorporating one of them to source the BaO instead is a
classic application of ceramic chemistry calculations.
- Barium carbonate is
commonly added to clay bodies in small amounts (0.2-0.8%) to halt fired
surface scumming or efflorescence It is slightly soluble in water and
provides Ba++ ions to link with SO4-- ions in the water to form BaSO4
(barium sulfate).
- Barium carbonate has
a wide variety of uses; it is used in the production of television
glass, crystal glass and special glass, frits and enamels, brick and
tile, ceramic, magnets, electrodes, barium salts, paper, rubber, marble
substitute and paints.
- It is also used for
removing sulfates mainly in phosphoric acid production and chlorine
alkali electrolysis and it is used as a rodenticide, an additive for
glaze, an analytical reagent, oxidizing agent and filler.
- Barium carbonate is
mainly used as a raw material in the electrical engineering industries
for glass production, a raw material in the magnet manufacturing
industry and as an additive in the ceramic industry in Korea.
- The estimated world
production volume of barite (BaSO4) among barium compounds was 5,890,000
tonnes/year.
