At temperatures of 600700 C, CoO oxidizes to the blue cobalt(II,III) oxide (Co3O4), which has a spinel structure.

It is a green diamagnetic solid that is soluble in water. cobalt(III) chloride is a salt with the formula CoCl 2 (en) 2Cl (en ethylenediamine).

Methods for manufacturing of cobalt boride coating layer on surface of steels by using a pack cementation process. ![]() ^ a b Yoon, Jin Kook Man, Jung Park, Sang Whan (2013).Handbook of Chemistry and Physics (91 ed.). Prior to reduction, the surface area of the catalyst is maximized by supporting the salt on another material often this material is activated carbon. When used as a catalyst, cobalt boride is prepared by reducing a cobalt salt, such as cobalt(II) nitrate, with sodium borohydride. Cobalt boride nanoparticles in the size range of 18 to 22 nm have also been produced. On to this iron boride coating is deposited cobalt using a pack cementation process. Coatings of cobalt boride on iron are produced by boriding, which involves first introducing a coating of FeB, Fe 2B. Preparations Materials coating Ĭobalt boride is produced under high temperature such as 1500 ☌. In one study, cobalt boride was found to be the most selective transition metal based catalyst available for the production of primary amines via nitrile reduction, even exceeding other cobalt containing catalysts such as Raney cobalt. Organic synthesis Ĭobalt boride is also an effective hydrogenation catalyst used in organic synthesis. Renewable energy Ĭobalt boride has also been studied as a catalyst for hydrogen storage and fuel cell technologies. These properties have been exploited in the field of biomedical sciences for the design of specialized drug delivery systems. For instance, studies suggest cobalt boride can increase the lifespan of metal parts when used as a coating, imparting surfaces with higher corrosion and wear resistance. These are refractory materials.Īpplications Materials science Ĭobalt borides are known to be exceptionally resistant to oxidation, a chemical property which makes them useful in the field of materials science. The two main cobalt borides are CoB and Co 2B. Cobalt borides are inorganic compounds with the general formula Co xB y. ![]()
