Barium chloride dihydrate (chemical formula BaCl2·2H2O) is an important inorganic chemical raw material with various industrial applications. The following sections introduce its uses in barium salt production, metal processing, electronics industry, chemical analysis, water treatment, and other fields:
1.Barium Salt Production
Barium chloride dihydrate is a crucial raw material for producing other barium salts (such as barium carbonate, barium sulfate, barium hydroxide, etc.). Through reactions with other chemicals, various barium compounds can be prepared, which are widely used in industries like ceramics, glass, pigments, rubber, and plastics.
2.Metal Processing
Heat Treatment Agent: In metal heat treatment processes, barium chloride dihydrate can be used as a quenching agent or barium impregnation agent to improve the hardness, wear resistance, and corrosion resistance of metal materials.
Welding Flux Aid: During welding, barium chloride dihydrate can be used as a flux aid to help remove oxides from the metal surface and improve welding quality.
3.Electronics Industry
Electronic Component Manufacturing: Barium chloride dihydrate can be used in the production of certain electronic components, such as capacitors and resistors.
Phosphor Materials: In the production of phosphor or luminescent materials, barium chloride dihydrate can serve as a dopant or raw material to improve the luminescent properties of the materials.
4.Chemical Analysis
Analytical Reagent: Barium chloride dihydrate can be used as a reagent in chemical analysis for the detection of sulfate ions, selenate ions, etc.
Chromatography: In chromatographic analysis, barium chloride dihydrate can be used as an additive in the stationary or mobile phase to enhance separation efficiency.
5.Water Treatment
Water Softening Agent: Barium chloride dihydrate can be used to soften hard water. By reacting with calcium and magnesium ions in the water, it forms insoluble barium salt precipitates, thereby reducing water hardness.
Wastewater Treatment: In wastewater treatment, barium chloride dihydrate can be used to remove heavy metal ions (such as lead, mercury, etc.) by precipitating them out of the water.
Barium chloride, as a fundamental chemical raw material, derives its core value from its unique precipitation capability and its role as the synthetic starting point for numerous important barium salts. It plays a crucial purification role in brine purification within the chlor-alkali industry, serves as the foundational raw material for producing precipitated barium sulfate, an important inorganic filler, and holds historical and applicative value in the fields of heat treatment (steel quenching) and metallurgy (magnesium alloy flux). Barium chloride occupies an irreplaceable position in safeguarding the smooth operation of fundamental industrial processes (such as chlor-alkali production) and providing key materials (such as high-grade pigment fillers). Its industrial significance is rooted in the specific solutions afforded by its chemical properties.
