English description（英文原文，共 1400 字符）
Product Name:Potassium Cobaltinitrite
English Name:Potassium Cobaltinitrite
CAS No.:13782-01-9
Aliases:Aureolin, Cobalt Yellow, Potassium hexanitritocobaltate(III), Fischer's salt
Molecular Formula:K3[Co(NO2)6]
Physical Properties:Yellow to yellowish-brown crystalline powder, odorless. Slightly soluble in cold water and insoluble in ethanol; decomposes in hot water or acids with evolution of nitrogen-containing gases. Density is about 1.94 g/cm³ at 20 °C. Decomposes when heated to approximately 200 °C. Stable in air, but the color darkens slightly under prolonged strong light exposure; store in airtight containers away from light.
Uses:It is mainly used in the manufacture of cobalt yellow pigment for watercolors, oil paints, ceramic glazes, and glass coloring. In the pyrotechnics industry, it serves as a flash suppressant and as a functional additive in various inorganic material formulations. It is also used in analytical chemistry as a characteristic precipitating reagent for the detection of potassium ions.
