    Product Description

    Lead(II) Bromide CAS 10031-22-8 is an inorganic lead halide, also known as lead dibromide or plumbous bromide, with molecular formula PbBr2, molecular weight 367.01 and EINECS 233-084-4.

    Synonyms: Lead dibromide; Plumbous bromide; Lead(2+) bromide; Dibromolead; PbBr2.

    CAS: 10031-22-8.

    It has the molecular formula PbBr2 and a molecular weight of 367.01 g/mol.

    It appears as a white to off-white crystalline powder with a density of about 6.66 g/cm³.

    It melts at about 373 °C and boils at about 916 °C.

    It has low solubility in cold water, which increases significantly in hot water, and is soluble in polar aprotic solvents such as DMSO and DMF.

    It is light-sensitive and can gradually darken or turn slightly yellow or grey on exposure.

    It is a primary precursor for organic-inorganic hybrid perovskites and wide-bandgap bromide perovskites in solar cells.

    High-purity crystals are used in X-ray and gamma-ray detection and imaging because lead and bromine provide useful high-energy photon stopping power.

    It is also used in infrared-transmitting glasses, optical fibers, laser materials and selected bromination reactions.

    Because it is a lead compound, it is classified as toxic and an environmental hazard and must be handled under professional controls.

    Use a HEPA-filtered respirator, nitrile gloves and safety goggles, and avoid inhalation of fine powder.

    Store in amber glass or opaque HDPE containers, cool and dry, ideally under an inert atmosphere for electronic applications.

    Confirm appearance, purity, lead and bromide assay, heavy-metal impurities and particle characteristics as required.

    Keep away from strong acids and oxidizing agents, and protect from moisture, light and dust.

    Confirm packaging with the requested quantity and destination requirements.

    FAQ - Technical & Supply Chain

    • Q:

      What is Lead(II) Bromide CAS 10031-22-8?

      A: Lead(II) Bromide CAS 10031-22-8 is an inorganic lead halide with molecular formula PbBr2, molecular weight 367.01, and EINECS 233-084-4. It is also known as lead dibromide or plumbous bromide and is commonly supplied as a white to off-white crystalline powder.
    • Q:

      Why is Lead(II) Bromide used as a perovskite solar cell precursor?

      A: PbBr2 provides lead and bromide ions for organic-inorganic hybrid perovskite layers and wide-bandgap bromide perovskites. Its purity can affect film quality, carrier lifetime, defect density, and final power conversion efficiency.
    • Q:

      How is Lead(II) Bromide used in X-ray and gamma-ray detection?

      A: Lead and bromine have relatively high atomic numbers, giving the material useful stopping power for high-energy photons. High-purity PbBr2 and lead-bromide perovskite crystals convert X-ray or gamma-ray signals into electrical responses for radiation detection and imaging.
    • Q:

      Why are DMSO and DMF solubility important for Lead(II) Bromide?

      A: PbBr2 has low cold-water solubility but dissolves in polar aprotic solvents such as DMSO and DMF. These solutions are used in spin-coating and other thin-film deposition routes to prepare uniform perovskite or photonic layers.
    • Q:

      Why should Lead(II) Bromide be stored away from light and moisture?

      A: Lead(II) Bromide is light-sensitive and can gradually darken or turn slightly yellow or grey when exposed. Keeping the container closed, dry, and away from direct light helps preserve its crystalline appearance and suitability for optoelectronic precursor use.
