RotoMetals Indium Ingot 99.99% Pure 1 Ounce

This is a one ounce bar of Indium. Its use is to mix with gallium and tin to create a liquid metal which can be put in various sized glass tubing to make thermometers and sphygmomanometers instead of highly toxic mercury. But then after further reading I found that gallium is corrosive so decided to just store this as an interesting specimen, since it is too soft to cast into jewelry. Oh well, not the indium’s fault.

Great piece of indium

I heard that maybe some people were getting cadmium instead of indium about 10 years ago. Things have changed. Rotometals is a reliable supplier of Indium (and bismuth, for what it's worth!) Does all the things that Indium does, like being really soft and squishy for a metal, able to cut it with scissors. Alloys well - I was able to use this for mixing up some Galinstan. I did experience a slight amount of garlic-smelling white vapor upon heating it past the melting point in a crucible with a torch, which gave me a bit of a headache. I think this is likely to be a slight arsenic or antimony impurity. Was able to burn off all of this contaminant and afterward the metal has no smell whatsoever and looks a little bit shinier.

Nice piece of Indium, ships in a small zip lock bag with their card (which had their website on it, it was actually quite a bit cheaper over there, wish I had checked!)

Definitely got what I laid for and couldn't be happier!

The price is pretty good considering how rare indium is. It's so soft you can bite a piece off and crush it into a cube fairly easily. A good addition to any element collection.

product was as advertised but its also cheaper on the sellers site with better photos of the actual product.

The image depicted does not match the actual product. Nonetheless, it does what is said on the label.
