Description
Barium chloride, with the chemical formula BaCl2, is an ionic chemical compound and one of the most important water-soluble salts of barium-containing compounds. It is a white solid, odorless, and hygroscopic substance. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. Barium chloride has wide applications in various industries and is used in the laboratory for various purposes.

Barium chloride is used in the manufacture of barium salts, paint pigments, and dyeing textiles. It is also used in the production of fireworks to give a bright green color.
Used in Electronics Industry:
Barium chloride is used in electronic instruments and calibration of instruments and devices, evaluation methodology, and quality assurance/quality control.
Used in Water Treatment:
Barium chloride is used for purification of brine solution in caustic chlorine plants, boiling water treatment, and as a component in a flux used to prevent oxidation of molten magnesium.
Used in Lubrication:
Barium chloride is used as a lubrication oil additive.
Used in Textile and Leather Industry:
Barium chloride is used in textile dyeing and for whitening leather.
Used in Aluminum and Magnesium Production:
Barium chloride is used in aluminum refining and production of magnesium metal or sodium metal.
Used in Laboratory:
Barium chloride is used as a dehydrating agent and analysis reagent. It is also used for machining heat treatment and as a component in various laboratory experiments.
Physical and Chemical Properties:
BaCl2 crystallizes in both the cubic "fluorite" and "lead chloride" crystal structures, accommodating the preference of the large Ba2+ ion for coordination numbers greater than six. Barium chloride (BaCl2·2H2O) is a colorless, white powder highly soluble in water (25% at 10 °C). It has a melting point of 963°C and is soluble in water, slightly soluble in hydrochloric acid and nitric acid, and very slightly soluble in alcohol.
Soluble barium salt
Barium chloride is one of the most important soluble barium salts, it is also known as "salting barium", the formula is BaCl2, it has colorless monoclinic and colorless cubic two crystals, monoclinic crystal turns into cubic crystal at 962℃. At room temperature it is white lustrous monoclinic crystal, odorless, bitter and salty. It is soluble in water, insoluble in acetone, ethanol and ether, slightly soluble in acid, sulfuric acid. Crystallization from aqueous solution of barium chloride often contains two crystal water. When heated to 113℃, it loses crystal water and becomes anhydrous barium chloride, it is white powder.
Barium chloride can be used for identification and separation of SO42-ions, purify the brine water, mainly used for the manufacture of barium salts and pigments, it can also be used as hard water softener, wool and leather industry mordant, pesticides for controlling plant pests. Preparation of industrial barium chloride is mainly used barite as material which containing high components of barium sulfate barite, coal and calcium chloride is mixed, and calcined to get barium chloride, reaction is as follows:
BaSO4 + 4C + CaCl2 → BaCl2 + CaS + 4CO ↑.
Hazardous characteristics
Barium chloride is noncombustible. It is highly toxic. When contacts boron trifluoride, violent reaction can occur. Swallowed or inhaled can cause poisoning, it is mainly through the respiratory tract and digestive tract to invade the human body, it will cause drooling and burning esophagus, stomach pain, cramps, nausea, vomiting, diarrhea, high blood pressure, no law firm pulse, cramps, a lot of cold sweat, weak muscle strength, gait, vision and speech problems, difficulty breathing, dizziness, tinnitus, consciousness usually clear. In severe cases, it can cause sudden death. Barium ions can cause muscle stimulant, then gradually transforms into paralysis. Rat oral LD50150mg/kg, mouse peritoneal LD5054mg/kg, rats are intravenously LD5020mg/kg, orally in dog LD5090mg/kg.
Production method
Barium chloride dihydrate is heated to above 150℃ by dehydration to obtain anhydrous barium chloride products. its
BaCl2 ? 2H2O [△] → BaCl2 + 2H2O
Preparation
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).
Air & Water Reactions
Water soluble.
Reactivity Profile
BARIUM CHLORIDE may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.
Hazard
Ingestion of 0.8 g may be fatal.
Fire Hazard
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.
Flammability and Explosibility
Nonflammable
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-.
Check Digit Verification of cas no
The CAS Registry Mumber 10361-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,3,6 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10361-37:
(7*1)+(6*0)+(5*3)+(4*6)+(3*1)+(2*3)+(1*7)=62
62 % 10 = 2
So 10361-37-2 is a valid CAS Registry Number.
