Buy CAS 10326-27-9 Barium ChlorideBaCl₂ for Industry Dehydrating Agent

Barium chloride (BaCl₂) is an important inorganic compound with the following key properties:

1. Chemical properties
Chemical formula: BaCl₂

Molecular weight: 208.23 g/mol

Chemical structure: consists of one barium ion (Ba² +) and two chloride ions (Cl⁻).

2. Physical properties
Appearance: White crystalline solid, usually in powder or particle form.

Density: 3.856 g/cm³ (anhydrous)

Melting point: 962°C (no water)

Boiling point: 1560°C (anhydrous)

Solubility: soluble in water, slightly soluble in ethanol and methanol. At 20°C,

about 35.8 grams per 100 ml of water can be dissolved.

Hygroscopicity: anhydrous barium chloride has hygroscopicity and easily absorbs moisture in the air.

3. Crystal structure
Crystal structure: anhydrous barium chloride belongs to the orthogonal crystal system,

and the dihydrate (BaCl₂·2H₂O) belongs to the monoclinic crystal system.

4. Chemical stability
Stability: Chemically stable at room temperature, but will decompose at high temperatures.

Reactivity: Reacts with sulfate to form barium sulfate precipitation, often used for the detection of sulfate ions.

5. Toxicity
Toxicity: Barium chloride is toxic, ingestion or inhalation will cause harm to human health,

should be handled with caution.

6. Application field
Chemical reagents: Used for laboratory analysis and chemical synthesis.

Water treatment: Used to remove sulfates from water.

Metal treatment: Used for metal surface treatment and heat treatment.

Manufacture of other barium salts: used as raw materials for the manufacture of other barium compounds.

Fireworks: Fireworks used to create a green flame.

7. Storage and handling
Storage: Store in a dry, well-ventilated environment to avoid moisture absorption.

Handling: Wear protective equipment during operation and avoid direct contact with skin and eyes.

Barium chloride application

1. Industrial use
To make other barium compounds:

Barium chloride is an important raw material for

preparing other barium salts (such as barium carbonate and barium sulfate).

Metal heat treatment:

In the heat treatment of metals, barium chloride is used as a quenching agent and as a component of molten salt baths.

Ceramics and Glass industry:

Used in the manufacture of specialty glass and ceramics to improve their optical properties and mechanical strength.

Pigment Manufacturing:

Barium chloride can be used in the production of certain pigments, such as barium chromate (yellow pigment).

2. Water treatment
Softening water:

Barium chloride can be used to remove sulfates (such as calcium sulfate, magnesium sulfate) from water,

resulting in an insoluble barium sulfate precipitate.

Wastewater treatment:

In industrial wastewater treatment, it is used to remove sulfate ions and other impurities.

3. Laboratory and scientific research
Analytical reagents:

Barium chloride is commonly used in chemical analysis. It detects the sulfate ion (SO₄²⁻).

It forms a white barium sulfate precipitate.

Also used to detect the chromate ion (CrO₄²⁻) and phosphate ion (PO₄³⁻).

Desiccant:

Barium chloride is hygroscopic and can be used as a desiccant.
