Thermochromic property of dichromate in liquid nitrogen

Author: Chattopadhyay, Dhrubojyoti

Keywords: Thermochromism
Chromogenic compounds

Issue Date: 2014-01

Publisher: National Council of Science Museums, Kolkata

Description: Thermochromism is the reversible colour change of a compound when it is heated or cooled. Thermochromic colour changed is distinguished by being quite noticeable, often dramatic and occurring over a small or sharp time interval. It is one of the important phenomena as it has bright future for industrial and practical use. North Bengal Science Centre regularly conducts liquid nitrogen shows for the public to demonstrate the behavior of materials at low temperatures. During the course of such shows it was observed that Ammonium dichromate exhibited thermochromic property at liquid nitrogen temperature possibly because of change in the band gap.

Description: Includes bibliographical references.
