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. | [Appearance]

| Hazard Information | Back Directory | [General Description]
Any of a variety of substances that contain barium. Most are whitish colored crystalline solids. They tend to be soluble in water and denser than water. They may be toxic by inhalation or possibly skin absorption. They are often used to make other chemicals. | [Reactivity Profile]

Water soluble. | [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. | [Physical properties]
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
“l(fā)ead chloride” crystal structures, both of which accommodate
the preference of the large Ba2+ ion for coordination
numbers greater than six. | [Definition]
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. | [Definition]
ChEBI: The inorganic dichloride salt of barium. | [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). | [Flammability and Explosibility]
Nonflammable | [Industrial uses]
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. |
| Questions And Answer | Back Directory | [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 ↑.
| [Chemical properties]
It is colorless monoclinic crystal. (Α type) it is soluble in water, slightly soluble in hydrochloric acid, nitric acid, very slightly soluble in alcohol. | [Uses]
(1) Barium chloride is mainly used for heat treatment of metals, barium salt manufacturing, electronic instruments, and used as water softener.
(2) It can be used as dehydrating agent and analysis reagents, it is used for machining heat treatment Jing, see other barium chloride dihydrate.
(3) Calibration instruments and devices, evaluation methodology, quality assurance/quality control. | [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
