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