Applications:
- in
the pre-treatment of brine used in Chlor-Alkali
industries. Brine used in Chlor-Alkali industries
in India contains excess Sulphates and other Metallic
Impurities when compared with world standards,
necessitiating a high degree of purification prior
to electrolysis to avoid damaging of the cell.
Treatment of the brine with Barium Carbonate removes
Sulphates as insoluble Barium Sulphate and Calcium
and Magnesium Salts as their insoluble Carbonates.
- in
the manufacture of the other Barium Compounds
such as Barium Chloride, Barium Nitrate and Barium
Sulphate.
- as
a fluxing ingredient in enamels, glazes and ceramic
bodies.
- in
the oil-well drilling industry to stabilise the
desired properties of the baryte suspension which
is used as drilling mud.
- in
the manufacture of photographic paper; to generate
Barium Sulphate in the paper which imparts a flat
white appearance.
- in
the glass industry, formulae containing various
percentages of Barium Oxide are used for several
purposes. To obtain Barium Oxide of requried percentage,
Barium Carbonate is added to the mix.
- in
the ferrous metallurgy, Barium Carbonate is used
in some systems for steel carborizing.
