Barium Chloride, identified by its CAS number 10361-37-2, is a significant inorganic compound with a wide array of industrial applications. As a key chemical intermediate, it is utilized across sectors ranging from pigments and dyes to water treatment and metallurgy. Understanding its properties, uses, and handling is crucial for professionals in these fields. We, as a leading Barium Chloride manufacturer in China, are committed to providing high-quality material and comprehensive information to our clients.

Chemical and Physical Properties:

Barium Chloride (BaCl₂) typically appears as a white powder or granular solid. It is highly soluble in water, with its solubility increasing significantly with temperature. For instance, at 20°C, approximately 35.8 grams dissolve in 100 mL of water, while at 100°C, this figure rises to 59.4 grams. It is also soluble in methanol but largely insoluble in ethanol. A notable characteristic is its hygroscopic nature, meaning it readily absorbs moisture from the air, necessitating storage in sealed containers. When exposed to a flame, Barium Chloride imparts a distinctive pale yellow-green color, a property leveraged in pyrotechnics.

The compound's chemical formula is BaCl₂, with a molar mass of approximately 208.23 g/mol for the anhydrous form and 244.28 g/mol for the dihydrate form. It is a stable compound under normal conditions but should be handled with care due to its toxicity.

Industrial Applications:

The versatility of Barium Chloride makes it indispensable in several key industries:

  • Pigment and Dye Manufacturing: It serves as a crucial precursor in the synthesis of various white pigments, such as lithopone, and is used in specific textile dyeing processes.
  • Water Treatment: Barium Chloride is widely employed for purifying industrial water, particularly in the caustic chlorine industry for the removal of sulfate ions from brine solutions, preventing scaling and equipment fouling.
  • Metallurgy: In the metallurgical sector, it finds application in case hardening of steel and as a component in heat treatment salts, improving surface hardness and material properties.
  • Chemical Synthesis: It acts as a foundational material for producing other barium salts and compounds.
  • Other Uses: Historically, it has been used as a test for sulfate ions in laboratory analysis and in the production of certain fireworks for its characteristic green flame.

Safety and Handling:

It is imperative to acknowledge that Barium Chloride is toxic. Ingestion, inhalation, or prolonged skin contact can lead to adverse health effects, including gastrointestinal distress, muscle dysfunction, and potential cardiac issues. Therefore, proper handling procedures are essential:

  • Always wear appropriate personal protective equipment (PPE), including gloves, eye protection, and dust masks, especially when handling the powder form.
  • Ensure adequate ventilation in areas where Barium Chloride is used.
  • Store the compound in tightly sealed containers in a cool, dry, and well-ventilated area, away from incompatible materials.
  • In case of spills or exposure, follow emergency protocols, which typically involve immediate medical attention and appropriate cleanup procedures.
  • Dispose of waste Barium Chloride according to hazardous waste regulations.
