Chromium Potassium Sulfate Dodecahydrate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar cells and fuel cells. American Elements produces to many standard grades when applicable, including Mil Spec ( grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

CHROMIUM POTASSIUM SULFATE/ USAGE

PHOTOGRAPHY
In photography, Chromium Potassium Sulfate is used as a mordant. It helps dyes to adhere to photographic films or papers, ensuring that the images have better color fastness and stability. It can form a complex with the dye molecules, improving the durability of the dye on the substrate and preventing the color from fading or changing over time.
TANNING INDUSTRY
In the tanning of leather, Chromium Potassium Sulfate is an important tanning agent. It reacts with the collagen in the leather to form stable cross-linking structures. This enhances the leather's resistance to water, abrasion, and microbial attack, making the leather softer, more durable, and more elastic, thus improving the quality and grade of the leather products.
TEXTILE INDUSTRY
It is used as a mordant in the textile dyeing process. It can interact with dyes and textile fibers, facilitating the dyes to attach better to the fibers. This results in more uniform and vibrant colors, as well as improved color fastness, ensuring that the dyed fabrics maintain their color and appearance after multiple washes and uses.
CHEMICAL REAGENT
Chromium Potassium Sulfate is often used as a chemical reagent in laboratories. It can be used in various chemical reactions and experiments, such as in the synthesis of other chromium compounds or as a catalyst in some reactions. It can also be used for the detection and analysis of certain substances due to its specific chemical properties.
WATER TREATMENT
In water treatment, it can be used to remove impurities and pollutants. It can hydrolyze in water to form colloidal substances such as chromium hydroxide, which can adsorb suspended impurities, organic matter, and heavy metal ions in the water. This helps to clarify the water, reduce turbidity and color, and improve the quality of the water.
CATALYST
It can be used as a catalyst or catalyst precursor in some chemical reactions. For example, in some organic synthesis reactions, Chromium Potassium Sulfate can participate in the preparation of catalysts that can effectively promote the progress of reactions, improve reaction selectivity and conversion rates.
ELECTROPLATING INDUSTRY
In the electroplating industry, it can be used in some chromium plating processes. It helps to provide chromium ions for the electroplating solution, enabling the deposition of chromium layers on the surface of metal objects, which can improve the corrosion resistance, wear resistance and appearance of the metal products.
PIGMENT INDUSTRY
It can be used in the production of pigments. Due to its chemical composition and properties, it can be used to prepare pigments with specific colors, which are widely used in the paint, ink, plastics and other industries to provide coloration and decoration effects.
