摘要：
A reversible temperature indicating material which is chemically stable, is not harmful and can be produced relatively inexpensively contains as principal component a polycrystalline bismuth-chromium oxide substance produced by firing a mixture with 50-86 molar % of bismuth-containing compounds and 50-14 molar % of chromium-containing compounds.
