Barium chloride Usage And Synthesis
- Soluble barium saltBarium 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 propertiesIt 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 characteristicsBarium 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.
- First-aid measureWhen skin contacts it, rinsing with water, then thoroughly washing with soap. When eye contacts, flushing with water. So that patients inhaled dust should leave from the contaminated area, move to fresh air place, rest and keep warm, if necessary, artificial respiration should be taken, seek medical attention. When swallowed, immediately rinse the mouth, gastric lavage should be taken with warm water or 5% sodium hydrosulfite for catharsis. Even swallows more than 6h, gastric lavage is also necessary. Intravenous infusion is slowly taken with 1% sodium sulfate of 500ml~1 000ml, intravenous injection can also be taken with 10% sodium thiosulfate of 10ml~20ml. Potassium and symptomatic treatment should be carried out.
Soluble barium salts of barium chloride is rapidly absorbed, so the symptoms develop rapidly, at any time cardiac arrest or respiratory muscle paralysis can cause death. Therefore, first aid must be against the clock.

- DescriptionBarium 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.
- Chemical PropertiesBarium 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.
- Physical propertiesBarium 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.
- UsesAs 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.
- UsesBarium 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.
- PreparationBarium 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
This first step requires high temperatures. The second step requires fusion of the reactants:
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).
- DefinitionChEBI: The inorganic dichloride salt of barium.
- Definitionbarium 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.

- Air & Water ReactionsWater soluble.
- Reactivity ProfileBARIUM CHLORIDE may react violently with BrF3 and 2-furan percarboxylic acid in its anhydrous form.

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.
- Industrial usesBarium 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.
