Coefficient of Thermal Expansion of Chromium (Cr) & Facts, Color, Uses ... 2022

Size of things changes depending on the coefficient of thermal expansion. It's even the case for Chromium. Ok, so what is the coefficient of thermal expansion for an atom of Cr?

Note: Learn more about the coefficient of thermal expansion here.

In the case of Chromium this thermal coefficient is 4.9 10^-6 K^-1. By the way, did you know there are cool facts about Chromium that most don't know? Check this...
