Overview
Lead(II) bromide is an inorganic compound consisting of lead and bromine in a 1:2 ratio. Its anhydrous form is preferred for industrial applications due to higher stability. Historically used in photography, modern applications leverage its optical and detection properties. The compound is synthesized by reacting lead(II) acetate with hydrobromic acid or through direct combination of lead and bromine. Industrial-grade material typically exceeds 99% purity, with trace metal impurities carefully controlled for specialized uses.
Physical and Chemical Properties
PbBr2 crystallizes in the orthorhombic system, forming layered structures that contribute to its cleavage properties. It exhibits photoluminescence under UV excitation, with emission peaks tunable by crystal size. The material's high atomic number (Z=82) gives it excellent radiation stopping power. Chemically, it demonstrates typical lead halide behavior - stable in dry air but slowly hydrolyzes in moisture. It forms complexes with halide ions (e.g., [PbBr4]2-) and reacts with strong acids. Thermal decomposition begins above 900°C, releasing bromine vapors.
Main Applications
In optics, PbBr2 serves as a precursor for perovskite materials in photodetectors and LED components. Single crystals are grown for gamma-ray spectroscopy due to their high stopping power and scintillation properties. The compound also catalyzes certain organic bromination reactions. Emerging applications include quantum dot synthesis and radiation shielding composites. In research, it's used to study heavy metal ion transport and crystal defect phenomena. Industrial consumption primarily comes from detector manufacturing and specialty glass production.
Safety and Storage
As a lead compound, PbBr2 requires strict handling protocols. OSHA permissible exposure limit (PEL) for lead is 0.05 mg/m³ (8-hour TWA). Always use NIOSH-approved respirators when handling powder and conduct operations in fume hoods. Store in chemically resistant containers (HDPE or glass) with desiccants. Incompatible with strong oxidizers and acids. Spills should be contained with absorbent materials and disposed as hazardous waste (D008 for lead content). Regular blood lead level monitoring is recommended for frequent handlers.
B2B Procurement Guide
Technical specifications should specify: 1) Purity (industrial grade ≥99%, electronic grade ≥99.9%), 2) Particle size (standard 100-200 mesh or custom), 3) Moisture content (<0.5% preferred), and 4) Heavy metal impurities. Request certificates of analysis (CoA) with ICP-MS data. Bulk shipments (25kg drums) typically offer 10-15% cost savings versus lab quantities. Consider suppliers with ISO 9001 certification and REACH compliance. For international shipments, verify IATA/IMDG classification (UN2291, 6.1). Sample testing for crystal structure (XRD) and purity (EDX) is recommended for first-time suppliers.
