    Barium dichloride is a white solid, odorless, hygroscopic chemical substance. Barium dichloride is used in the manufacture of pigments, in the manufacture of other barium salts and in fireworks to give a bright green color. It is one of the most common watersoluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. Barium chloride has wide application in the laboratory.

    ??? ??

    Barium chloride,BaCI2, is a colorless toxic salt with a melting point of 963°C. It is soluble in water. Barium chloride is used in metal surface treatment and as a rat poison.

    ??? ??

    Barium chloride has the formula, BaCl2 and is an ionic chemical compound. It is one of the most important water-soluble salts of barium-containing compounds. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. It is also hygroscopic. Barium chloride was the by-product of the discovery of radium by Madame Curie (1898).When refining radium, the final separation resulted in barium chloride and radium chloride. BaCl2 crystallizes in both the cubic “fluorite” and “lead chloride” crystal structures, both of which accommodate the preference of the large Ba2+ ion for coordination numbers greater than six.

    ??

    As a cheap, soluble salt of barium, barium chloride finds wide application in the laboratory. It is commonly used as a test for sulfate ion. In industry, barium chloride is mainly used chiefly in the synthesis of pigments and in the manufacture of rodenticides and pharmaceuticals. It is also used:
    In the purification of brine solution in caustic chlorine plants.
    In the manufacture of heat treatment salts.
    For case hardening of steel.
    In the manufacture of pigments.
    In the manufacture of other barium salts such as barium hydroxide.
    In fireworks to give a bright green color. However, its toxicity limits its applicability.
    As a flux in the manufacture of magnesium metal.
    For making color kinescope glass ceramics.
    In wastewater treatment.
    For the production of PVC stabilizers, oil lubricants, barium chromate and barium fluoride.
    For stimulating the heart and other muscles for medicinal purposes.
    For softening water.
    For manufacturing of other barium salts used as pesticides, pigments, boiler detergent.
    As a mordant in dyeing and printing textiles.
    In the manufacture of caustic soda, polymers, and stabilizers.

    ??

    Barium chloride (BaCl2) is used in the manufacture of paint pigments and dyeing textiles and as an additive in oils. It is also used as a water softener.

    ?? ??

    Barium chloride can be prepared from barium hydroxide or barium carbonate, the latter being found naturally as the mineral “Witherite”. These basic salts react to give hydrated barium chloride. On an industrial scale, it is prepared via a two-step process from the mineral “Baryte”:
    BaSO4+4C→BaS+4CO (gas)
    This first step requires high temperatures. The second step requires fusion of the reactants:
    BaS+ CaCl2→BaCl2+CaS
    The BaCl2 is then be leached out from the mixture with water. From water solutions of barium chloride, the dihydrate can then be crystallized as white crystals, BaCl2·2H2O, which are colorless, translucent rhomboidal tablets or lamellae. The dihydrate is stable in the air at room temperature, but loses one-half of its water above 55°C(131F), and becomes anhydrous at 121°C (250 F).

    barium chloride: A white compound,BaCl2. The anhydrous compoundhas two crystalline forms: anα form (monoclinic; r.d. 3.856),which transforms at 962°C to a βform (cubic; r.d. 3.917; m.p. 963°C;b.p. 1560°C). There is also a dihydrate,BaCl2.2H2O (cubic; r.d. 3.1),which loses water at 113°C. It is preparedby dissolving barium carbonate(witherite) in hydrochloric acid andcrystallizing out the dihydrate. Thecompound is used in the extractionof barium by electrolysis.

    BARIUM CHLORIDE may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.

    ???

    Ingestion of 0.8 g may be fatal.

    ????

    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.

    ?? ??

    Barium chloride (BaCl2·2H2O) is a colorless, white powder highly soluble in water (25% at 10 °C). It is quite a toxic reagent. Barium chloride is used during borite flotation as an activator. Barium chloride also has a depressing effect on fluorite and cassiterite.

    Safety Profile

    A poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Inhalation absorption of barium chloride equals 60-80%; oral absorption equals 10-30%. Experimental reproductive effects. Mutation data reported. See also BARIUM COMPOUNDS (soluble). When heated to decomposition it emits toxic fumes of Cl-.
