Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the ... 82 Pb lead; use: 600.61 K: 327.46 °C: 621.43 °F WEL: 600.61 K:
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. ... Lead: 11.342: 600.61: 2,022 ...

Soldering copper pipes using a propane torch and a lead-free solder. Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties. Hence a wide range of solder alloys exist, and only major ...
In the past, it was an alloy of tin and lead, but most modern pewter, in order to prevent lead poisoning, is not made with lead. Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals.
Melting point: 1,113 [1] °C (2,035 °F; 1,386 K) Boiling point: ... Lead(II) sulfide (also spelled sulphide) is an inorganic compound with the formula Pb S.
Reaction of lead with sulfur or hydrogen sulfide yields lead sulfide. The solid has the NaCl-like structure (simple cubic), which it keeps up to the melting point, 1114 °C (2037 °F). If the heating occurs in presence of air, the compounds decomposes to give the monoxide and the sulfate. [7]
