Preparation method and application of chromium sulfide Cr2S3 powder

Overview of chromium sulfide Cr2S3 powder

Cadmium sulfide is an inorganic substance with a chemical formula of CdS. There are two crystals, the α-form is a lemon yellow powder, and the β-form is an orange-red powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. It can be used to make fireworks, glass glazes, enamels, luminescent materials, and pigments. High-purity cadmium sulfide is a good semiconductor, has a strong photoelectric effect on visible light, and can be used to make photoelectric tubes and solar cells. Pass hydrogen sulfide into the acid solution of cadmium salt.

Chromium sulfide powder is an inorganic compound formulated as Cr2S3. Chromium sulfide is a brown-black solid, insoluble in water. Chromium sulfide is usually a non-stoichiometric compound with a molecular formula ranging from CRS to Cr0.67S (corresponding to Cr2S3). Chromium sulfide is usually a non-stoichiometric compound with a molecular formula of Crs to Cr0.67 (corresponding to Cr2S3). 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). Some metal-metal bonds have a Cr-Cr distance of 2.78 A.

Chromium sulfide Cr2S3 powder is a medium water-soluble and acid-soluble chromium source, compatible with sulfate. Sulfates are sulfates or esters formed by replacing one or two hydrogens with metals. 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. The organometallic form is soluble in organic solutions, and sometimes soluble in water and organic solutions.

Chromium (III) sulfide Cr2S3 powder can be prepared by reacting a stoichiometric mixture of chromium powder and sulfur powder elements at 1000°C.

Or take chromium and sulfur with a molar ratio of 2:3, heat it in vacuum for 1 day, then cool, crush, heat in vacuum, and then slowly cool. Place Cr2S3 briefly at 300°C and then cool to room temperature.

Application of chromium sulfide Cr2S3 powder

It is widely used for the coloring of enamel, glass, ceramics, plastics and paint. It is also used in coatings and plastics industries, as well as electronic fluorescent materials. Cadmium yellow is suitable for coloring almost all resins, and it is translucent in plastics. The light-colored cadmium yellow containing zinc sulfide is used in polyethylene, and the molding and 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 not as stable as cadmium red in the room, and it is mostly used in indoor plastic products. Cadmium yellow should not be combined with pigments containing copper or copper salts, so as to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow and blue pigments can be mixed together to get green.

High-purity sulfide, used in battery materials and semiconductor materials. It can be used as chemical reagents, fine chemicals, pharmaceutical intermediates, and material intermediates.
