What is the color of Chromite flour 325mesh 400mesh 600mesh 800mesh?
Chromite flour is made by crushing and grinding natural iron chromite ore, which has a glossy black color. After grinding, more chromium and iron elements in the chrome ore are released, which has a significant impact on the color.
Firstly, the color of chromium metal and chromium oxide turns green. When chromium ore is ground to 325mesh -400 mesh, the color of chromite powder will turn dark green.
Then, chromite is finely ground to 600mesh-800 mesh. The released iron oxide in the powder oxidizes upon contact with air, resulting in a darker reddish black color of the chromite powder.
Therefore, the finer the Iron Chromite flour of 400mesh -800 mesh, the redder the color of its black material.
