High-purity sulfide, used in battery materials and semiconductor materials. Cadmium yellow and blue pigments can be mixed together to get green. Cadmium yellow should not be mixed with pigments containing copper or copper salts to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow is not as stable as cadmium red indoors, and is mostly used in indoor plastic products. The light-colored cadmium yellow containing zinc sulfide is used for polyethylene, and the molding processing time should be shortened as much as possible, because zinc sulfide will promote the decomposition of polyethylene plastic and make it green. Cadmium yellow is suitable for coloring almost all resins, and it is translucent in plastics. Chromium sulfide Cr2S3 is also used in the coating and plastic industries, as well as electronic fluorescent materials. Place Cr2S3 briefly at 300☌ and then cool to room temperature.Īpplication of chromium sulfide Cr2S3 powderĬhromium sulfide Cr2S3 is widely used for the coloring of enamel, glass, ceramics, plastics and paint. Or take chromium and sulfur in a molar ratio of 2:3, heat it in vacuum for 1 day, then cool, crush, heat in vacuum, and then slowly cool.
The organometallic form is soluble in organic solutions, and sometimes soluble in water and organic solutions.Ĭhromium (III) sulfide Cr2S3 powder can be prepared by reacting a stoichiometric mixture of chromium powder and sulfur powder elements at 1000☌.
Unlike fluorides and oxides, which are often insoluble in water, most metal sulfate compounds are easily soluble in water and used for water treatment and other purposes. Sulfates are sulfates or esters formed by replacing one or two hydrogens with metals. Some metal-metal bonds have a Cr-Cr distance of 2.78 A.Ĭhromium sulfide Cr2S3 powder is a medium water-soluble and acid-soluble chromium source, compatible with sulfate. According to X-ray crystallography, chromium sulfide is a combination of nickel arsenide (stoichiometric ratio 1:1) and cadmium (OH) 2 (stoichiometric ratio 1:2). Chromium sulfide is usually a non-stoichiometric compound with a molecular formula of Crs to Cr0.67 (corresponding to Cr2S3). Chromium sulfide is usually a non-stoichiometric compound with a molecular formula ranging from CRS to Cr0.67S (corresponding to Cr2S3). Chromium sulfide (III) Cr2S3 powder is an inorganic compound with the molecular formula Cr2S3. Chromium sulfide is a brown-black solid, insoluble in water. Overview of chromium sulfide Cr2S3 powderĬhromium sulfide powder is an inorganic compound formulated as Cr2S3. This substance may be harmful to the environment, so special attention should be paid to water bodies. Properties: brown, there are two kinds of trigonal crystal system and orthorhombic crystal system.ĭensity (g/mL, 25/4℃): 3.972g/cm3 (trigonal crystal system), 3.922g/cm3 (rhombic crystal system) The physical properties of chromium sulfide Place it at 300☌ for a short time, and then cool to room temperature to get Cr2S3. After heating in a vacuum for 1 day, it is cooled, crushed, heated in a vacuum, and slowly cooled. Take chromium and sulfur and mix it with a molar ratio of 2:3. Can be used as chemical reagents, fine chemicals, pharmaceutical intermediates, material intermediates Please let us know how we can improve this web app.Chromium (III) sulfide is an inorganic substance with the chemical formula Cr2S3.
