Application

Lead iodide finds application in synthesis of perovskites based photovoltaic materials. Our perovskite grade PbI2 can readily be dissolved in DMF to yield 1M solution.

Lead iodide (PbI2) is a salt with the chemical formula PbI2

 It is also known as plumbous iodide, lead (II) iodide, or lead diiodide.

 At room temperature, lead iodide is a bright yellow, odorless, crystalline solid. When heated, it turns orange and red.

Lead iodide is almost insoluble and precipitates

Lead iodide is the most common iodide of lead. It is an ionic compound.

Lead iodide is harmful if swallowed or inhaled. It may cause cancer, damage fertility or the unborn child, and damage organs through prolonged or repeated exposure. It is also very toxic to aquatic life.

Borun New Material is a manufacturer of perovskites , which are organic optoelectronic materials. Perovskites have unique properties, such as high resistivity and chemical stability.

Is PbI2 an element or compound?

PbI2 is an ionic compound with the formula PbI2. It is also known as lead(II) iodide or plumbous iodide. 

PbI2 is a bright yellow crystalline solid at room temperature. When heated, it becomes orange and red. It has a wide band gap value of 2.27 eV. 

PbI2 is used in the manufacture of solar cells, X-ray and gamma-ray detectors. It is also used in a patented photographic process. It was formerly used as a yellow pigment in some paints, but this use has been largely discontinued due to its toxicity and poor stability. 

PbI2 is made up of two chemical elements: lead (Pb) and iodine (I). Lead carries a +2 charge and forms an ionic bond with iodine to form the compound. 

Does PbI2 dissolve in water?

Lead iodide (PbI2) is a yellow crystalline solid that is insoluble in water. It is also denser than water. When placed in water, lead iodide establishes the following equilibrium: 

PbI2 (s) ↔ Pb2+ (aq) + 2I- (aq) 

The solubility of lead iodide in water is 0.44 g/L at 0°C, 0.76 g/L at 20°C, and 4.1 g/L at 100°C. 

Lead iodide is also insoluble in other solvents. 

Is lead II iodide ionic or covalent?

Lead iodide is an ionic compound. It's made up of a lead cation and an iodide anion. The lead (II) cation has a +2 charge. 

Lead iodide is also known as plumbous iodide. It's a bright yellow, heavy powder that's odorless. It's denser than water and is insoluble in most liquids, except for boiling water and potassium iodine. 

Lead iodide is used in bronzing, gold pencils, mosaic gold, printing, and photography.
