| Hazard Information | Back Directory | [General Description]
A yellow crystalline solid. Insoluble in water and denser than water. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment. Used in printing and photography, to seed clouds and other uses. | [Reactivity Profile]
LEAD IODIDE(10101-63-0) has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive. Light sensitive | [Air & Water Reactions]
Slightly water soluble. | [Health Hazard]
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract. Pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact with eyes causes irritation. | [Potential Exposure]
Lead iodide is used in bronzing, gold
pencils; mosaic gold; printing, and photography | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomi | [Shipping]

Yellow hexagonal crystals; density 6.16 g/cm3; melts at 402°C; vaporizes at 954°C; decomposes at 180°C when exposed to green light; slightly soluble in water (0.44 g/L at 0°C and 0.63 g/L at 20°C); K下sp 8.49x10-9 at 25°C; partially soluble in boiling water (4.1 g/L at 100°C); insoluble in ethanol; soluble in alkalis and alkali metal iodide solutions. | [Uses]
Bronzing, gold pencils, mosaic gold, printing, photography. | [Uses]
Lead(II) iodide is used as a detector material for high energy photons including x-rays and gamma rays. It is used in photography, printing, mosaic gold, and bronzing. It exhibits ferroelastic properties and has efficiency in stopping X-ray and gamma ray, which provides excellent environmental stability. | [Uses]
Used in bronzing, printing, photography, and mosaic gold | [Preparation]
Lead diiodide is prepared by mixing aqueous solutions of lead nitrate or lead acetate with an aqueous solution of potassium or sodium iodide or hydriodic acid, followed by crystallization. The product is purified by recrystallization.

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Lead iodide must be stored to avoid contact withoxidizers (such as perchlorates, peroxides, permanganates,chlorates, and nitrates) and chemically active metals (suchas potassium, sodium, magnesium, and zinc), since violentreactions occur. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045. Lead iodide isregulated by an OSHA Standard, 1910.1025. All requirements of the standard must be followed. | [Purification Methods]
It crystallises from a large volume of water. The solubility in H2O is 1.1% at ~10o, and 3.3% at ~ 100o. |
| Questions And Answer | Back Directory | [Description]
Lead (II) iodide (chemical formula: PbI) is a kind of inorganic
salt. It appears as a bright yellow crystalline solid. It has some
special applications such as the manufacture of solar cells, X-rays,
and gamma-ray detectors. In addition, it can also be used as a paint
pigment for being used in art for bronzing and in gold-like mosaic
tiles. It can be commonly synthesized through a double displacement
reaction between potassium iodide KI and lead (II) nitrate Pb(NO3)2
in water solution. Lead (II) acetate and sodium iodide can also be
used as the substitute of lead nitrate and potassium iodide,
respectively. Alternatively, it can be manufactured through the
reaction between iodine vapor and the molten lead. It is also used
in printing and photography. However, it is hazard to the
environment, and should be taken care of to limit spread to the
environment. | [References]
