Paper Abstract

Silver mercury tetraiodide (Ag,HgI ) is a well known thermochromic pigment that changes color from yellow to ornge at 50 C. The compound is also a fast ion conductor above its phase transition temperature. We synthesized a number of analogues of this compound in which the silver was replaced by cadmium, lead, thallium(I), copper(I), indium(I), gold(I), lithium, cesium and rubidium to determine the range of color transitions and the correlation of electrical conductivity with optical and thermal activity. This paper also reports on continued research to assess the possibility of using these pigments in architectural coatings.
