Buy CAS 10326-27-9 Barium ChlorideBaCl₂ White Crystal for Papermaking

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.

How about barium chloride paper making

1. Potential applications
Fillers and coatings: Barium chloride can be used as paper fillers and coatings to improve the gloss

and smoothness of paper.

Water treatment: In the papermaking process, barium chloride can be used to remove sulfates from water

and prevent equipment scaling.

2. Problems and limitations
Toxicity: Barium chloride is toxic and has potential hazards to operators and the environment.

Strict protection is required.

Environmental impact: The use of barium chloride may lead to water pollution,

and the discharge should be strictly controlled.

Cost: The high price of barium chloride increases the production cost.

Alternatives: There are safer, environmentally friendly alternatives such as calcium carbonate and talc.

3. Safety and environmental measures
Protective measures: Wear protective equipment during operation and avoid direct contact.

Waste treatment: The waste liquid should be discharged after treatment to meet the standards to

prevent environmental pollution.

Compliance with regulations: Comply with relevant environmental regulations to ensure safe production.

conclusion
The application of barium chloride in the paper industry is limited, mainly due to its toxicity

and environmental effects. The modern paper industry prefers to use safe and environmentally friendly alternatives.

 If barium chloride is to be used, strict safety and environmental protection measures must be taken.
