Title: Termochoromic compound changing colours from orange to red
Post by: Vargulf on July 27, 2017, 07:32:49 AM

Does anyone know a termochoromic compound which changes their color from orange to red, while getting heated? This compound includes Hg and probably KOH. Thank you for helping me. I could  not find any compound like this in the web.
