Physical Data

Appearance Grey Metal Granules, Shot, Foil, Sheet Or Powder

Melting Point 327.4-328ºC

 

Lead is a silver white heavy metal with blue, melting point 327.502 C, boiling point 1740 C, density 11.3437 g / cm 3, hardness 1.5, soft texture and small tensile strength.

The lead color without oxidation layer is bright, high density, very low hardness, and strong extensibility. It has very low conductivity and high corrosion resistance, so it is often used as a container for corrosive substances (such as sulphuric acid). A small amount of antimony or other metal can be added to improve its corrosion resistance.

Metal lead is affected by oxygen, water and carbon dioxide in the air, and its surface will oxidize quickly to produce protective film.

Under heating, lead can quickly combine with oxygen, sulfur and halogen.

Lead can hardly react with cold hydrochloric acid or cold sulfuric acid, it can react with heat or concentrated hydrochloric acid and sulfuric acid, lead react with dilute nitric acid, but it does not react with concentrated nitric acid, and lead can slowly dissolve in strong alkaline solution.

 

Industrial method

Cerussite

White lead mine

The first one: lead Pyrometallurgy

At present the world to lead pyrometallurgy of lead, lead pyrometallurgy generally includes raw material preparation (mixing, granulating, sintering, smelting) preparation of crude lead and refining of crude lead three processes. An important part of sulphuric acid, soot and comprehensive recovery of metals from anode slime gold and silver and other precious fire lead smelting process.

 

Main uses

Lead is widely used in many industry fields, it is widely used in plumbing and anti-corrosion lining acid industry, battery, cable wrapping and metallurgical industry equipment.

Lead can absorb radioactive rays and can be used as protective materials for atomic energy industry and X - ray instruments.

Lead can be formulated with antimony, tin, bismuth and other various alloys, such as fuse, printing, wear-resisting alloy bearing alloy, solder, shrapnel projectile, fusible alloy and low melting point alloy mould etc..

A lead compound for tetraethyl lead gasoline antiknock additives and pigments.

It can be used as the sound insulation of the building industry and the shock proof material on the equipment.
