Metalworking Grade 99% Barium Chloride BaCl₂ for Improve Surface Finish Quality

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

• Chemical formula: BaCl₂
• Molecular weight: 208.23 g/mol
• Chemical structure: consists of one barium ion (Ba² +) and two chloride ions (Cl⁻)

• Appearance: White crystalline solid, usually in powder or particle form
• Density: 3.856 g/cm³ (anhydrous)
• Melting point: 962°C (anhydrous)
• Boiling point: 1560°C (anhydrous)
• Solubility: soluble in water, slightly soluble in ethanol and methanol
• Hygroscopicity: anhydrous barium chloride has hygroscopicity and easily absorbs moisture

Anhydrous barium chloride belongs to the orthogonal crystal system, and the dihydrate (BaCl₂*2H₂O) belongs to the monoclinic crystal system.

• Stable at room temperature, decomposes at high temperatures
• Reacts with sulfate to form barium sulfate precipitation

Barium chloride is toxic. Ingestion or inhalation can cause harm to human health. Handle with caution.

• Chemical reagents for laboratory analysis and synthesis
• Water treatment to remove sulfates
• Metal surface treatment and heat treatment
• Raw material for manufacturing other barium compounds
• Fireworks production for green flame effects

• Store in dry, well-ventilated environment
• Wear protective equipment during operation
• Avoid direct contact with skin and eyes

• Reagent for sulfate ion detection (SO₄²⁻)
• Used to prepare buffer solutions for pH stabilization

• Intermediate for pharmaceutical raw materials
• Precipitating agent for drug purification

• Sulfate detection in biological samples
• Historical contrast media research (now replaced by safer alternatives)

• Highly toxic - strictly control dosage
• Modern medicine uses safer barium salts like barium sulfate
