Chromium Oxide Powder (Cr2O3) occurs in nature as a rare mineral called eskolaite. These nanoparticles are predominantly used as dyes. Some of the synonyms of chromium oxide nanoparticles are chromsaeureanhydrid, trioxochromium, monochromium trioxide, chromia, green cinnabar, chrome ochre and chromtrioxid. Chromium belongs to Block D, Period 4 while oxygen belongs to Block P, Period 2 of the periodic table.

Chromium Oxide Powder (Cr2O3) is an important refractory material due to its high melting temperature (about 2300◦C) and oxidation resistance; although its sinter-ability is very poor and requires special sintering condition to achieve high density. For such an application, the availability of nano sized powders would be desirable since they usually present high surface areas and may favor the sintering process.

Chromium Oxide Powder is used as a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and wear-resistant materials. It is used in coatings of bearings, seals, orifices, and valve seals, and as a fine-crystal phase in other sintered carbides, where, like the vanadium carbide, it inhibits growth of submicrometre grains during pressing and sintering.

Chromium Oxide Powder can combine to form many different compounds which have uses in welding and thermal spraying. As well as these current applications of chromium carbide, the material has potential as a more environmentally friendly replacement for hard chromium plating.

Chromium Oxide Powder Diamalloy powders are characterized by their ability to provide wear, oxidation and hot corrosion resistance at elevated temperatures. The NiCr cladding improves corrosion properties. Higher NiCr content results increased fracture toughness of the coatings.
