Product infomation

Introduce

Lead is a chemical element in the periodic table abbreviated as Pb (Latin: Plumbum) and has the atomic number 82. Lead has a common valence of II, sometimes IV. Lead is a soft, heavy, toxic and formable metal. Lead is bluish-white when freshly cut but begins to tarnish to gray when exposed to air. Lead is used in construction, lead batteries, ammunition, and is part of many alloys. Lead has the highest prime number of the stable elements.

Characteristics

Lead is silvery white and bright, its fresh cut surface slag rapidly in the air giving it a dark color. It is a bluish-white metal that is very soft, malleable and heavy, and has poor electrical conductivity compared to other metals. Lead is highly resistant to corrosion, and because of this property, it is used to contain corrosive substances (such as sulfuric acid). Because of its malleability and corrosion resistance, it is used in construction works such as in roofing sheets. Metallic lead can be hardened by adding small amounts of antimony, or small amounts of other metals such as calcium.
Lead powder burns to a bluish-white flame. Like many metals, very fine lead sets are capable of spontaneous combustion in air.[6] Toxic fumes are emitted when lead burns.

Application

- Lead is the main component of batteries used in vehicles.
- Lead is used as a white pigment in paints.
- Lead is used as a coloring ingredient in enamels, especially in red and yellow colors.
- Lead is used as a barrier to prevent nuclear radiation.
- Lead is commonly used in PVC.
