Calcium Bromide (CaBr₂)

1. Overview
Calcium Bromide (CaBr₂) is an inorganic compound widely used in industrial, oilfield, and chemical applications. It appears as a white crystalline solid or colorless liquid (in solution form), highly soluble in water and alcohol. Its hygroscopic nature and high-density properties make it valuable in multiple sectors.

2. Key Specifications

  • Chemical Formula: CaBr₂

  • Molecular Weight: 199.89 g/mol

  • Appearance: White powder, flakes, or clear liquid

  • Purity: Typically 95%–99% (technical grade) or ≥99% (high-purity grade)

  • Density: ~3.35 g/cm³ (solid), 1.5–1.7 g/cm³ (liquid solutions)

  • Melting Point: 730°C (1,346°F)

3. Applications

  • Oil & Gas Drilling:

    • Used as a denseclear brine fluidin completion and workover operations to stabilize high-pressure wells.

    • Compatible with zinc bromide and calcium chloride blends for adjustable density (up to 19.2 lb/gal).

  • Deicing & Dust Control:

    • Effective as aroad deicer(low freezing point: −50°C/−58°F) and dust suppressant.

  • Chemical Synthesis:

    • Intermediate in bromine compound manufacturing (e.g., flame retardants, pharmaceuticals).

  • Food & Medicine:

    • Food additive (E238 preservative) and electrolyte in veterinary medicines.

4. Packaging & Storage

  • Solid Form: 25 kg bags, 1 MT big bags, or customized pallets.

  • Liquid Form: IBC totes (1,000 L), drums (200 L), or bulk tankers.

  • Storage: Keep sealed in dry, cool conditions to prevent moisture absorption.

5. Safety & Handling

  • Non-flammablebut may irritate skin/eyes (wear PPE: gloves, goggles).

  • Environmental Note: Biodegradable; avoid release into waterways.
