Image of cobalt metal[edit]

Is the image of cobalt metal included in this article really cobalt? I looked online for more images of Cobalt metal and all the other pictures I have seen look much more silvery and much less golden.

Addition: The image is the same as on the Iron page. — Preceding unsigned comment added by 62.92.247.101 (talk) 09:53, 20 September 2023 (UTC)[reply]

Iron
Cobalt

The images for iron and cobalt are not the same image. They were uploaded by Alchemist-hp who has uploaded many excellent images of elements, many of which have been assessed as the best quality images on commons. I'm certain the image is indeed cobalt.

This is right. Iron chis are iron chips and cobalt chips are cobalt chips. Take an exact look on a calibrate monitor, so you can see the difference: cobalt is redish and iron more silvery. --Alchemist-hp (talk) 19:13, 26 October 2023 (UTC)[reply]

Medical uses[edit]

Hey Guys

In medical uses of cobalt you should mention its use as an Implant material. Its used as for dental implants when alloyed with chromium and molybdenum, refered to as "CoCrMo" in scientific journals or "Vitalium" as a tradename

Cobalt Poisining of firefighters due to a lithium battery fire[edit]

In Victoria (Australia), two firefighters have been permanently disabled as a result of heavy metal poisoning when they absorbed cobalt compounds from a lithium battery fire. Unfortunately, I have no further details, which is why I havent added this to the main article. 2001:8003:E490:7D01:70EE:4AFD:8B72:B12F (talk) 06:11, 17 March 2023 (UTC)[reply]
