Chemische Eigenschaften
Lead fluoride is a white to colorless, odorless
crystalline (rhombic, orthorhombic) solid
Verwenden
Lead(II) fluoride is used in fuses, glass coatings to reflect infrared rays and phosphors for television screens and in low melting glasses. Further, it serves as a catalyst for the preparation of picoline.
Application
It is used as the transmission window in λ: 250 nm–10 mm and as the prism in the infrared region.
Allgemeine Beschreibung
Odorless white solid. Sinks in water.
Reaktivit?t anzeigen
Calcium carbide mixed with Lead fluoride , at ordinary temperatures, becomes incandescent [Mellor 5:862-64. 1946-47].
Health Hazard
Not irritating to skin or mucuous membranes; protect against chronic poisoning. 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.
Brandgefahr
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
m?gliche Exposition
Used to make other chemicals, underwater paints; electronic and optical parts (for growing
single-crystal, solid-state lasers); in high-temperature dryfilm lubricants; and making special grades of glass.
