Metalworking Grade 99% Barium Chloride BaCl₂ for Improve Surface Finish Quality
Barium chloride (BaCl₂) is an important inorganic compound with the following key properties:
1. Chemical properties
Chemical formula: BaCl₂
Molecular weight: 208.23 g/mol
Chemical structure: consists of one barium ion (Ba² +) and two chloride ions (Cl⁻).
2. Physical properties
Appearance: White crystalline solid, usually in powder or particle form.
Density: 3.856 g/cm³ (anhydrous)
Melting point: 962°C (no water)
Boiling point: 1560°C (anhydrous)
Solubility: soluble in water, slightly soluble in ethanol and methanol. At 20°C,
about 35.8 grams per 100 ml of water can be dissolved.
Hygroscopicity: anhydrous barium chloride has hygroscopicity and easily absorbs moisture in the air.
3. Crystal structure
Crystal structure: anhydrous barium chloride belongs to the orthogonal crystal system,
and the dihydrate (BaCl₂·2H₂O) belongs to the monoclinic crystal system.
4. Chemical stability
Stability: Chemically stable at room temperature, but will decompose at high temperatures.
Reactivity: Reacts with sulfate to form barium sulfate precipitation, often used for the detection of sulfate ions.
5. Toxicity
Toxicity: Barium chloride is toxic, ingestion or inhalation will cause harm to human health,
should be handled with caution.
6. Application field
Chemical reagents: Used for laboratory analysis and chemical synthesis.
Water treatment: Used to remove sulfates from water.
Metal treatment: Used for metal surface treatment and heat treatment.
Manufacture of other barium salts: used as raw materials for the manufacture of other barium compounds.
Fireworks: Fireworks used to create a green flame.
7. Storage and handling
Storage: Store in a dry, well-ventilated environment to avoid moisture absorption.
Handling: Wear protective equipment during operation and avoid direct contact with skin and eyes.
What role does barium chloride play in medicine
1. Laboratory research
Reagent:
Barium chloride is used as a chemical agent in the laboratory for the detection of sulfate ions (SO₄²⁻) :
A white precipitate (barium sulfate) is generated for qualitative or quantitative analysis.
Buffer:
In some experiments, barium chloride can be used to prepare buffer solutions to stabilize pH.
2. Drug synthesis
Intermediate:
Barium chloride can be used as an intermediate for the synthesis of some drugs or pharmaceutical raw materials.
Precipitating agent:
In the drug purification process, barium chloride can be used to precipitate impurities or separate target compounds.
3. Medical testing
Sulfate detection:
In medical laboratories, barium chloride is used to detect the sulfate content of biological samples (e.g. urine, blood).
Contrast media research:
Barium chloride was once used as a research contrast agent,
but has been replaced by safer barium salts (such as barium sulfate) due to its toxicity.
4. Historical application
Pharmaceutical Ingredients:
In the past, barium chloride was used in certain drugs, but it is no longer used due to its toxicity.
Pesticides:
Barium chloride was once used to make insecticides,
but it has been eliminated because of its harm to the environment and human body.
5. Precautions
Toxicity:
Barium chloride is toxic to humans and can cause serious health hazards if ingested or inhaled.
When used in the medical field, the dosage should be strictly controlled to avoid contact with the skin and eyes.
Alternatives:
Due to the toxicity of barium chloride, more safe barium salts (such as barium sulfate) are used in modern medicine.
