Cuprous selenide (Cu₂Se) lump is a high-purity semiconductor compound known for its excellent thermoelectric properties, electronic conductivity, and optical characteristics. It is widely used in photovoltaic cells, infrared detectors, energy conversion technologies, and advanced material research. Due to its superior properties, cuprous selenide plays a crucial role in sustainable energy applications, precision electronics, and specialized engineering solutions.
Product Description
Cuprous Selenide (Cu₂Se) is a black cubic crystal with a melting point of 1113°C and a relative density of 6.749. It is soluble in potassium cyanide solution and releases hydrogen selenide when dissolved in hydrochloric acid. When reacted with sulfuric acid, it releases sulfur dioxide gas. Cuprous Selenide has wide reactivity in chemistry and can be oxidized to copper selenite using nitric acid. This compound is typically produced by heating copper and selenium under vacuum conditions or by reducing copper salts with ammoniacal selenous acid using hydrazine.
