化学的特性
white, ortho-rhomb crystal(s); -80 mesh with 99.999% purity; enthalpy of vaporization 133 kJ/mol; enthalpy of fusion 16.44 kJ/mol; obtained from PbO or PbCO3 and HBr; finds use as a photopolymerization catalyst and in photoduplication processes in the 365 nm region [KIR78] [CER91] [CRC10] [MER06]
物理的性質
White orthorhombic crystals; density 6.66 g/cm
3; melts at 373°C; forms a horn-like mass on solidification; vaporizes at 916°C; decomposes slowly on exposure to light; sparingly soluble in cold water (4.55 g/L at 0°C and 8.44 g/L at 20°C, respectively); moderately soluble in boiling water (44.1g/L at 100°C); Ksp 6.60x10
-6 at 25°C; insoluble in alcohol; slightly soluble in ammonia; soluble in alkalies and also in sodium or potassium bromide solutions.
使用
It is used in the field of antirust, pigment and photograph. The molten lead(II) bromide acts as an electrolyte. Lead(II) bromide provides a high concentration of lead(II) ions and bromide ions to carry the current during the electrolysis process. The rare-earth-doped alkali-lead bromide crystals (potassium lead bromide (or) KPB; rubidium lead bromide or RPB) emerge as promising new low-phonon-energy host materials for mid-IR applications and are useful for solid state lasers. Hybrid organic/lead halide perovskites are promising materials for solar cell fabrication.
純化方法
Crystallise it from water containing a few drops of HBr (25mL of water per gram PbBr2) between 100o and 0o. A neutral solution is evaporated at 110o, and the crystals that separate are collected by rapid filtration at 70o and dried at 105o (to give the monohydrate). Its solubility in H2O is 0.5% (at ~10o) and 5% (at ~ 100o). To prepare the anhydrous bromide, the hydrate is heated for several hours at 170o and then in a Pt boat at 200o in a stream of HBr and H2. Finally it is fused [Clayton et al. J Chem Soc, Faraday Trans 1 76 2362 1980].
