Indium is a very soft, silvery-white metal with a brilliant lustre. The pure metal gives a high-pitched "scream" when bent. It wets glass, as does gallium. It is useful for making low-melting alloys. An alloy of 24% indium and 76% gallium is liquid at room temperature. Canada produces the majority of of the world's supply of indium.

Indium is never found as the free element. Indium usually is associated with zinc minerals, and these form the commercial sources of most indium. It is also found in iron, lead, and copper ores

My Story

Indium:

would not normally be made in the laboratory as it is commercially available

is a byproduct of the formation of lead and zinc

metal is isolated by the electrolysis of indium salts in water

~~~~~~~~~~~~~~~~~~~~~~~~~
Further processes are required to make very pure indium for electronics purposes.

Date of Discovery: 1863
Discoverer: Ferdinand Reich
Name Origin: From the Indigo color seen in its spectrum
Uses: coating of high-speed bearings
Obtained From: by-product of zinc refining

My Job

I am used in:

making bearing alloys

germanium transistors
rectifiers
thermistors
photoconductors
it can be plated onto metal and evaporated onto glass, forming a mirror as good as those made with silver, but with more resistance to atmospheric corrosion
photocells
making low-melting alloys, alloyed with gallium
solders

comprehensive aspects of indium : on one page.
I have used indium / lead solder... but now with Europe being lead free.
My need now is to have indium / tin or purify my indium.
I need help on gettting the indium out of my indium / lead 50 / 50
help please GerwingR@HOTMAIL.COM//
