응용 분야
출처Cadmium sulfide occurs in nature as the mineral greenoktite. The compound is widely used in pigments for paints, baking enamels, ceramics and plastics. It imparts bright yellow to maroon, with strong retention of color and resistance to alkalis. It also is used in inks, phosphors, and fluorescent screens. Other applications of this compound are in photovoltaic and solar cells (for converting solar energy to electrical energy), photoconductors (in xerography), thin film transistors and diodes, rectifiers, scintillation counters, pyrotechnics, and smoke detectors.
역사The discovery of cadmium sulphide is linked to that of the element cadmium. In 1817, the German chemist Friedrich Stromeyer, while examining samples of zinc carbonate, observed that upon heating, they turned yellow rather than the white colour expected for pure zinc oxide. Through further investigation, he isolated a new metal oxide and identified the presence of a previously unknown element, cadmium, associated with the zinc compounds.
용도cadmium sulfide is used as a colorant for paints and rubber; cadmium acetate is used in the production of craftware.
일반 설명Natural occurrence: hawleyite (structural type of sphalerite) and greenockite (structural type of wurtzite)
제조 방법
생산 방법Cadmium sulfide may be prepared by the reaction between hydrogen sulfide and cadmiumvapor at 800 Cor by heating a mixture of cadmium or cadmium oxide with sulfur.
Cadmium sulfide may be prepared by precipitation from an aqueous solution of its soluble salts such as cadmium chloride or cadmium nitrate by passing hydrogen sulfide. The reactions may be carried out in acidic, neutral or alkaline solutions using various cadmium salts to obtain different crystal modifications as shown in the table below. Cadmium sulfide also may be obtained by treatment of sodium or other alkali metal sulfide solution with that of a soluble cadmium salt. The compound also may be prepared by heating a mixture of cadmium or its oxide with sulfur at 800°C; or by the reaction of H2S with cadmium vapor at 800°C.
