Chemical Properties:

STABILITY: Relatively stable at room temperature, but may react chemically at high temperatures or in specific chemical environments. For example, it will decompose when heated to a certain temperature, producing lead and bromine gas.

Reactivity: can react with some reducing agents and be reduced to metallic lead; react with some oxidising agents and bromide ions may be oxidised.

Uses:

Analytical reagent: in chemical analysis, Lead Bromide can be used to detect and analyse certain substances. For example, it is used to detect the presence of halogen ions, silver ions, etc.

Optoelectronic materials: due to its special optical and electrical properties, Lead Bromide can be used to produce optoelectronic materials, for example, it has certain applications in the field of solar cells, photodetectors and so on.

Thermoelectric Semiconductor Materials: Lead Bromide can be used as one of the components of thermoelectric semiconductor materials for the manufacture of thermoelectric conversion devices, which convert thermal energy into electrical energy.
