1. Performance Chemicals

• Barium Titanate: Barium chloride is a key ingredient in the production of barium titanate (BaTiO₃), which is a ferroelectric material used in capacitors and other electronic devices.
• Laboratory reagent: It is a versatile reagent used in various chemical synthesis, particularly for producing other barium compounds and in specific laboratory applications.

2. Water Treatment

• Sulfate removal: It is used in wastewater treatment primarily to remove sulfate ions. It's also used to purify brine solutions in caustic chlorine plants and in the production of other barium salts.
• Brine Purification: In caustic chlorine plants, barium chloride helps to purify brine solutions by removing impurities like sulfates.

3. Metal Treatment

• Heat Treatment Salts: It is a key component in the production of heat treatment salts, which are used in processes like carburizing and case hardening of steel.
• Case Hardening of Steel: It is used in the case hardening process, which involves heating steel to a high temperature in a molten salt bath to increase the hardness of its surface.

4. Fabric Solutions

• Mordant: It acts as a mordant, meaning it helps to bind the dye molecules to the fabric fibers. This improves the adhesion of the dye and prevents it from washing away or fading.
• Colorfastness and Durability: By enhancing the dye's attachment to the fabric, barium chloride contributes to the colorfastness and durability of the dyed textile.
