99% International Class ChlorideBaCl₂ White Crystal for Leather Industry

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 is mainly used for tanning and dyeing in the leather industry,

and the following are its specific applications and precautions:

1. Tanning
Function: Barium chloride as an auxiliary tanning agent, help tanning agent better penetrate the leather fiber,

improve the tanning effect.

Application: Used in chrome tanning and vegetable tanning.

2 .Dye
Function: As a mordant, barium chloride helps the dye to better adhere to the leather and improve the dyeing effect.

Application: Suitable for dyeing all kinds of leather products.

3. Process steps
Pretreatment: Before tanning or dyeing, the leather is treated with barium chloride solution to

enhance the adsorption capacity of the tanning agent or dye.

Tanning or dyeing process: barium chloride is added to the tanning solution or dye bath to

promote the binding of the tanning agent or dye to the leather fibers.

Post-treatment: After tanning or dyeing, use barium chloride solution to fix the color and enhance the dyeing fastness.
