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.
