About Chromium Sulfide Cr2S3 Powder :
Chromium sulfide powder is an inorganic compound formulated as Cr2S3.
What is the name of Cr2S3? 
Chromium sulfide is a brown-black solid insoluble in water.
Is chromium sulfide an ionic compound? 
Chromium(III) Sulfide is the inorganic compound with the formula Cr2S3. Chromium sulfides are usually nonstoichiometric compounds, with formulas ranging from CrS to Cr0.67S (corresponding to Cr2S3). Chromium sulfide is usually a non-stoichiometric compound with molecular formulas ranging from Crs to Cr0.67 (corresponding to Cr2S3). According to X-ray crystallography, chromium sulfide is a combination of nickel arsenide (1:1 stoichiometric ratio) and cadmium (OH)2(1:2 stoichiometric ratio). The Cr-Cr distance of some metal-metal bonds is 2.78 A. Feel free to send an inquiry to get the latest price if you would like to buy Chromium Sulfide Cr2S3 Powder in bulk.

How is Chromium Sulfide Cr2S3 powder produced?
Chromium sulfide is a moderately water-soluble and acid-soluble chromium source, compatible with sulfates. Sulfate is a sulfate or ester formed by replacing one or two hydrogens with a metal. Most metallic sulfate compounds are readily soluble in water and used for purposes such as water treatment, unlike fluorides and oxides which tend to be insoluble in water. Organometallic forms are soluble in organic solutions and sometimes in water and organic solutions.
Chromium sulfide (III) can be prepared by reacting a stoichiometric mixture of chromium powder and sulfur powder elements at 1000°C.
Or by taking chromium and sulfur according to the molar ratio of 2∶3 mixed, heated in vacuum 1 day later, cooling, crushing, and then heating in vacuum, and slowly cooling.Cr2S3 is obtained by placing it briefly at 300℃ and then cooling it to room temperature.
 
Applications of Chromium Sulfide Cr2S3 Powder:
Chromium sulfide in water will undergo a double hydrolysis reaction to produce chromium hydroxide and HS-, and even H2S.

Storage Condition of Chromium Sulfide Cr2S3 Powder:
The damp reunion will affect Cr2S3 powder dispersion performance and using effects, therefore, Chromium Sulfide Cr2S3 Powder should be sealed in vacuum packing and stored in a cool and dry room, the Chromium Sulfide Cr2S3 Powder can not be exposure to air. In addition, the Cr2S3 powder should be avoided under stress.
