Buying Guide: Barium Chloride Dihydrate (BaCl₂·2H₂O)

If Barium Chloride Dihydrate is an essential material in your industrial operations—such as water treatment, heat treatment of metals, or chemical synthesis—this guide is designed to help you make informed purchasing decisions.
Barium Chloride Dihydrate is a highly versatile inorganic salt, used extensively in a wide variety of industries due to its solubility, reactivity with sulfates, and strong ability to form precipitation products. It is especially valuable in the production of pigments, heat-treating salts, and in the purification of brine solutions.
Description
Barium Chloride Dihydrate (BaCl₂·2H₂O) is a white crystalline solid with a salty, slightly bitter taste. It is odorless, soluble in water, and has good thermal stability. Its high purity (≥99.0%) makes it suitable for both general industrial use and more specialized applications in metallurgy and water treatment.
It is widely used in sectors such as electroplating, pigment manufacturing, chemical processing, wastewater treatment, and laboratory reagent production.

Is Barium Chloride Dihydrate Corrosive?
Yes. It is corrosive to metals and can be harmful to skin and mucous membranes on contact. It reacts with acids to release toxic fumes and should be handled with caution.
Precautions:
-
Avoid contact with moisture or acids.
-
Use corrosion-resistant containers and equipment.
-
Always wear appropriate PPE (gloves, goggles, respirators).
Is Barium Chloride Dihydrate Toxic?
Yes. Barium Chloride Dihydrate is toxic when ingested or inhaled. It affects the nervous system and muscles by interfering with potassium ion transport.
Safe Handling Guidelines:
-
Work in a well-ventilated environment.
-
Use protective equipment (chemical gloves, face shield, respirator).
-
Strictly follow MSDS guidelines and local safety regulations.
-
Keep away from food products and animal feed.
Is Barium Chloride Dihydrate Explosive?

No, it is not explosive. However:
-
It may produce flammable hydrogen gas when reacting with metals in acid.
-
Contact with incompatible substances (sodium, potassium, etc.) should be avoided.
-
Store in cool, dry, and well-ventilated conditions.
