Calcium Bromide Powder – Overview
Calcium Bromide Powder (chemical formula: CaBr₂) is a white, crystalline, hygroscopic (moisture-absorbing) solid commonly used in industrial, oilfield, and chemical applications. It is highly soluble in water and alcohol, making it useful in various liquid-based solutions.
Key Properties of Calcium Bromide Powder
- Appearance: Fine white powder or granules
- Odor: Odorless
- Solubility:
- Water: Highly soluble (over 1,400 g/L at 20°C)
- Alcohol & Acetone: Soluble
- Hygroscopicity: Absorbs moisture from air (must be stored in airtight containers)
- Density: ~3.35 g/cm³
- Melting Point: ~730°C (1,346°F)
- pH (in solution): Neutral to slightly acidic
Primary Uses & Applications
- Oil & Gas Drilling Fluids
- Used as a high-density clear brine fluid in well completion and workover operations to stabilize pressure and prevent blowouts.
- Preferred over alternatives like calcium chloride due to higher density (up to 1.7 g/cm³ in solution).
- Deicing & Dust Control
- Effective for road deicing in cold climates (less corrosive than chloride salts).
- Helps suppress dust on unpaved roads.
- Food Industry (E227)
- Acts as a preservative and firming agent in some foods (regulated use).
- Chemical Manufacturing
- Used in photography, flame retardants, and bromine-based chemical synthesis.
- Medicine & Pharmaceuticals
- Occasionally used in sedatives and anticonvulsant formulations.
- Laboratory & Industrial Processes
- Serves as a drying agent (desiccant) due to its hygroscopic nature.
Handling & Safety
- Storage: Keep in airtight, moisture-proof containers to prevent clumping.
- Health Hazards:
- May cause skin/eye irritation (use gloves & goggles).
- Inhalation of dust can irritate the respiratory tract.
- Environmental Impact:
- Generally low toxicity but should be handled responsibly to avoid water contamination.
Why Choose Calcium Bromide Powder?
- High solubility & density make it ideal for oilfield brines.
- Less corrosive than chlorides for deicing applications.
- Versatile in chemical and industrial processes.
Calcium Bromide Liquid – Overview
Calcium Bromide Liquid is a clear, colorless to light yellow aqueous solution of calcium bromide (CaBr₂). It is widely used in industrial applications, particularly in oil & gas drilling, due to its high density and stability at elevated temperatures.
Key Properties
- Appearance: Clear, colorless to pale yellow liquid
- Odor: Slight (typically odorless)
- Density: Adjustable (typically 1.5–1.7 g/cm³, higher than water)
- Solubility: Fully miscible with water; compatible with some alcohols
- Freezing Point: Depends on concentration (lower than water due to brine properties)
- pH: ~6–8 (neutral to slightly alkaline)
- Hygroscopic: Absorbs moisture if exposed to air
Primary Uses & Applications
1. Oil & Gas Industry (Major Use)
- Drilling & Completion Fluid:
- Used as a high-density brine (up to 1.7 g/cm³) to control well pressure and prevent blowouts.
- Preferred over calcium chloride in high-temperature wells due to better stability.
- Workover & Packer Fluids:
- Maintains wellbore stability during maintenance operations.
2. Deicing & Dust Control
- Road Deicing: Effective at lower temperatures than plain salt.
- Dust Suppression: Used on unpaved roads and construction sites.
3. Industrial & Chemical Processes
- Bromine Source: Used in chemical synthesis and flame retardants.
- Heat Transfer Fluid: In some industrial cooling systems.
4. Food Industry (Limited Use, E227)
- Preservative & Firming Agent (regulated for specific food applications).
5. Other Uses
- Fire Retardants (in some formulations).
- Laboratory Reagent (in chemical reactions).
Advantages Over Solid Calcium Bromide
✅ Ready-to-use (no mixing required).
✅ Consistent density & concentration (precisely controlled).
✅ Easier handling & storage compared to hygroscopic powder.
Handling & Safety
- Storage: Keep in HDPE (plastic) or corrosion-resistant steel tanks (avoid aluminum).
- Corrosivity: Less corrosive than chlorides but can still degrade some metals.
- Health Hazards:
- Skin/Eye Contact: May cause irritation (use PPE).
- Ingestion: Harmful if swallowed in large amounts.
- Environmental Impact:
- Low toxicity but should be contained to prevent runoff into water systems.
Typical Concentrations & Grades
| Grade | Concentration | Density (g/cm³) |
|---|---|---|
| Industrial Grade | 52–54% CaBr₂ | ~1.7 |
| Oilfield Grade | 95%+ purity | Adjustable (1.4–1.7) |
| Food Grade (E227) | Highly purified | Varies |
Why Choose Calcium Bromide Liquid?
✔ Superior for oilfield applications (high density, thermal stability).
✔ More efficient than powder for deicing & dust control.
✔ Consistent quality & easy to pump in industrial processes.
