Cobalt boride Cobalt boride Cobalt borides are inorganic compounds with the general formula CoB. The two main cobalt borides CoB and CoB. These are refractory materials. Cobalt boride is known to be exceptionally resistant to oxidation, a chemical property which makes compound useful in the field of materials science. 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 properties have been exploited in the field of biomedical sciences for the design of specialized drug delivery systems. Cobalt boride has also been studied as a
Cobalt(II) nitrate Cobalt(II) nitrate Cobalt Nitrate is the Inorganic compound with the formula Co(NO3)xHO. It is cobalt(II) salt. The most common form is the hexahydrate Co(NO)·6HO, which is a red-brown deliquescent salt that is soluble in water and other polar solvents. As well as the anhydrous compound Co(NO), several hydrates of cobalt(II) nitrate exist. These hydrates have the chemical formula Co(NO)·"n"HO, where "n" = 0, 2, 4, 6. Anhydrous cobalt(II) nitrate adopts a three-dimensional polymeric network structure, with each cobalt(II) atom approximately octahedrally coordinated by six oxygen atoms, each from a different nitrate ion. Each nitrate ion coordinates to three cobalts. The
