Chromium dust is a silvery white metal with a dark gray color. It’s a cubic-centered body-centered crystal system.
Particle size 53-125um(FSSS).
Chromium Cr Cr Powder
The chrome-colored steel-gray chromium can be used for making stainless steel as well as many other alloys. The color of glass is also given by Chromium. Chromium is resistant to oxidization in the atmosphere, even when exposed to extreme moisture.
What is Chromium powder?
The silvery-white Chromium powder has a dark gray color due to the body-centered cubic-crystal system. Chromium melting points are 1857. HTMLromium boiling point – 2672
Chromium densityD28 7.20. Dissolves in dilute phosphoric acid or dilute hydrochloric Acid. Insoluble in water. A chemical symbol for Chromium is Cr. This element has anatomic number of 24, and falls under the VIB group on the periodic table. The Greek word that means “color” is used to name the element. Chromium compounds also have colors. Steel-gray metal is the single most abundant material. It is the strongest metal found in nature. The Earth’s crust has 0.01% chromium. This ranks it 17th. It is rare to find chromium naturally in the crust of the earth. It causes almost no harm to the human body. It is however carcinogenic. Products should be packed in steel drums with lined polyethylene plastic bags. Acids should not be transported or stored together. Use dry powdered sand or water to extinguish fire.

How is Chromium Cr Puffer made?
Chromium production involves the conversion of chromium tetraoxide to sodium citrate by the calcination method of chromite.
For electrolysis methods: the sodium chromate compensation solution for electrolysis is 40g/L (Cr), 90g/L (6NH4). The anodic and cathode solutions for chloride are 22g/L each (Cr) at approximately 60 degrees C, a cell voltage 4.8V, and current density 8.6A/CrR12. It is a high-content chromite with aluminum and silicon as well other impurities, so the amount that’s released during the process can be large.
It is now possible to use this method to convert chromite from carbon to carbon ferrochrome. Once that is done, the sodium chromate solution can be obtained by roasting with dolomite or soda ash. The sulfur will reduce the oxide to chromium, which can then be calcined and reduced. Aluminum is then added and sandblasted. This approach has advantages: Most of the chromium impurities are removed from the smelting mixture, so that there is less pollution.

Chromium has many uses . A light-resistant coating can be applied to Chromium powder. This can also be used in abrasives as well as glass and ceramic colorants. For leather tanning, dyeing, impregnating, or other purposes, dichromate and chlorium alum can be used. A chromizing process that uses chrome plating to make aluminum, steel and copper corrosion-resistant can also be used. The result is bright and beautiful and widely applied in furniture design, car construction, building and other industries. Chromium ore also is widely used to make refractory compounds. For refining high temperature alloy, resistance alloy, precision alloy and as an additon to chromium element. The electroplating process uses pure chromium.
Storage condition of chromium Cr pulver:
Weakened chromium Cr particles will cause a damp reunion, which can adversely affect their dispersion performance. You should also avoid stressing the Cr powder.
