4N5 Indium Ingots

Indium is a soft, ductile, malleable, lustrous metallic metal. Its color is silvery white and it has a face-centered tetragonal structure. It is liquid over a wide range of temperatures, like gallium that belongs to its same group. Both indium and gallium are able to wet glass. Indium is stable in air and in water but dissolves in acids. When heated above its melting point it ignites burning with a violet flame.

Indium is not widely dispersed in the environment. It produced in industry comes as the by-product of smelting zinc and lead sulfide ores.
