Industrial Grade 99% Barium Chloride BaCl2 White crystal for Chemical Materials

• Appearance: Colorless or white crystalline solid
• Molecular weight: 244.26 g/mol (BaCl₂*2H₂O)
• Density: 3.097 g/cm³ (25°C)
• Melting point: about 120°C (loss of crystal water), anhydrous barium chloride melting point is 962°C
• Solubility: Soluble in water, solubility increases significantly with temperature (about 37 g/100 mL water at 20°C)
• Hygroscopicity: Barium chloride dihydrate is stable in air, but anhydrous barium chloride has strong hygroscopicity

• Stability: Stable at room temperature, but when heated to about 120°C it loses its crystal water and transforms into anhydrous barium chloride (BaCl₂)
• Acid-alkaline: The aqueous solution is neutral
• Reactivity: Reacts with sulfate ions (SO₄²⁻) to form white barium sulfate (BaSO₄) precipitation (commonly used to detect sulfate ions)
• Reacts with chromate ions (CrO₄²⁻) to form yellow barium chromate (BaCrO₄) precipitation
• Reacts with carbonate ions (CO₃²⁻) to form white barium carbonate (BaCO₃) precipitation

• Laboratory reagents: Used to detect sulfate, chromate, and carbonate ions; as a buffer or standard substance
• Industrial Applications: Used in manufacture of other barium compounds (barium carbonate, barium sulfate), water treatment, metal heat treatment and ceramic industry
• Other uses: Used to make green fireworks and as an intermediate for certain drugs in medicine

• To make other barium compounds: Important raw material for preparing other barium salts (barium carbonate, barium sulfate)
• Metal heat treatment: Used as quenching agent and component of molten salt baths
• Ceramics and Glass industry: Used in manufacture of specialty glass and ceramics to improve optical properties and mechanical strength
• Pigment Manufacturing: Used in production of certain pigments like barium chromate (yellow pigment)

• Softening water: Used to remove sulfates (calcium sulfate, magnesium sulfate) from water, forming insoluble barium sulfate precipitate
• Wastewater treatment: Used in industrial wastewater treatment to remove sulfate ions and other impurities

• Analytical reagents: Commonly used in chemical analysis to detect sulfate, chromate and phosphate ions
• Desiccant: Due to its hygroscopic properties, can be used as a desiccant

• Medical Imaging: Barium sulfate (prepared from barium chloride) used as X-ray contrast agent for gastrointestinal examinations
• Drug synthesis: Intermediate in some pharmaceutical compounds
