What applications does Chromium Metal have in industry?

Chromium is used primarily in the metallurgy industry to provide corrosion resistance and a shiny finish.

In alloys, for example, stainless steel that contains more than 8% chromium.

In chrome plating processes (depositing a protective layer by electroplating). It is also used in the anodizing of aluminum.

 

Chromates and oxides are used as mordants in colorants and paints, due to their varied colors.

Potassium dichromate (K2Cr2O7) is a chemical reagent used in cleaning laboratory glassware and as a titrant in volumetric analysis.

 

The use of chromium and some of its oxides as catalysts is common, for example, in the synthesis of ammonia (NH3).

The mineral chromite (Cr2O3 · FeO) is used in molds for the manufacture of bricks (in general, to manufacture refractory materials). However, a good part of the chromite consumed is used to obtain chromium alloys.

In leather tanning it is common to use the so-called "chrome tanning" in which chromium (III) hydroxysulfate (Cr (OH) (SO4)) is used.

 

To preserve the wood, chemical substances are used that are fixed to the wood, protecting it. Chromium (VI) oxide (CrO3) is used among these substances.

When some aluminum ions are replaced by chromium ions in corundum (α-Al2O3), ruby is obtained; this gem can be used, for example, in lasers.

 

Chromium dioxide (CrO2) is used to make the magnetic tapes used in cassettes, giving better results than with iron oxide (Fe2O3) due to their greater coercivity.

What is Chromium Metal? and its importance on the planet.

Chromium is a chemical element with atomic number 24 that is found in group 6 of the periodic table, and is characterized by being a hard, brittle transition metal, steely gray in color and highly resistant to corrosion.

There are four natural isotopes of chromium which are, 50Cr, 52Cr, 53Cr, 54Cr, and various unstable isotopes have been produced by radiochemical reactions. The most important is 51Cr, which emits weak gamma rays and has a half-life of approximately 27 days.

Chromium Metal, How are its characteristics?

 

Its mechanical properties, including its hardness and tensile strength, determine the usability of the substance. It has a relatively low forging and winding capacity, however when it is absolutely free of oxygen, hydrogen, carbon and nitrogen it is very ductile and can be forged and handled.
