Main industries include:
· Steel heat treatment
· Welding materials
· Chemical manufacturing
· Barium salt production
· Industrial water treatment
Yes. It is highly soluble and dissociates as:
BaCl₂ → Ba²⁺ + 2Cl⁻
· Anhydrous (BaCl₂): no water, suitable for high-temperature processes
· Dihydrate (BaCl₂·2H₂O): contains crystal water, more stable for general use
Because it contains no crystal water, it:
· Prevents explosive splashing at high temperature
· Improves furnace stability
· Ensures safer operation
· Provides consistent heat transfer
It is mainly used in:
· Metal heat treatment (salt bath furnaces)
· Welding flux production
· Barium salt manufacturing
· Chemical synthesis processes
· Industrial water treatment
It is widely used in high-temperature industrial applications.
