Antimony ( Sb - 630.5°c )

 

Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic luster.

Antimony is used in semiconductor technology for making infrared detectors, diodes, and Hall-effect devices and used in alloys with percentages ranging from 1 to 20 - greatly increases the hardness and mechanical strength of lead. Also used in batteries, antifriction alloys, type metal, small arms and tracer bullets, cable sheathing, and minor products use about half the metal produced. When alloyed with tin, antimony makes a type of pewter.

Pure Antimony Ingot

Uses

Around 50% of pure antimony currently produced is used for hardening lead, to make alloys which are then used (mostly) in batteries. However, the hardened alloy also finds use in small arms bullets (and tracer rounds) and cable sheathing among others. Babbitt metal, an alloy of tin, copper and antimony is used in machine bearings due to its hard but slippery, lubricant properties. Antimony is finding applications as a semiconductors.The brilliant yellow colour of antimony oxide means it is used as a pigment in paints, rubbers, plastics, etc.
