Calcium Bromide Powder (CaBr₂) – Properties, Uses & Safety
Calcium bromide powder is the solid, crystalline form of calcium bromide (CaBr₂), widely used in chemical synthesis, oilfield applications, and pharmaceuticals. Below are its key characteristics and applications.
Properties of Calcium Bromide Powder
- Chemical Formula: CaBr₂ (anhydrous) or CaBr₂·xH₂O (hydrated)
- Appearance: White to off-white crystalline powder
- Molar Mass:
- Anhydrous: 199.89 g/mol
- Dihydrate (CaBr₂·2H₂O): 235.98 g/mol
- Solubility: Highly soluble in water (~143 g/100 mL at 20°C)
- Melting Point: ~730°C (anhydrous)
- Hygroscopicity: Absorbs moisture from air (should be stored in sealed containers)
Common Uses of Calcium Bromide Powder
1. Oil & Gas Industry
- Used to prepare high-density brine fluids (when dissolved in water) for well drilling and completion.
- Often blended with zinc bromide (ZnBr₂) for ultra-high-density solutions (SG >2.3).
2. Pharmaceutical & Medical Applications
- Sedative & Anticonvulsant: Historically used in medicine (now largely replaced by safer drugs).
- Veterinary Medicine: Occasionally used for calming animals.
3. Chemical Synthesis
- Brominating Agent: Used in organic chemistry to introduce bromide groups.
- Electrolyte Production: For batteries and electrochemical processes.
4. Photography & Fire Retardants
- Formerly used in photographic emulsions (silver bromide).
- Acts as a flame retardant in some polymers.
How to Prepare Calcium Bromide Solution?
To make a liquid solution:
- Dissolve CaBr₂ powder in water (e.g., 52% solution for oilfield use).
- Filter to remove impurities (if needed).
- Adjust density (typically 1.5–2.3 g/cm³) depending on application.
Safety & Handling
- Skin Contact: May cause mild irritation (wash with water).
- Eye Contact: Rinse immediately (can cause irritation).
- Ingestion: Can lead to bromism (neurological effects like drowsiness, confusion).
- Storage: Keep in airtight containers (hygroscopic).
Where to Buy Calcium Bromide Powder?
- Chemical Suppliers: Syntech.
- Industrial Suppliers: Alibaba (bulk quantities, oilfield-grade).
- Pharmaceutical Grade: Specialized chemical manufacturers.
