General comment Niobium oxide, sometimes called columbium oxide, refers to the general formula Nb 3n+1 O 8n−2 where n ranges from 5 - 8 inclusive, e.g. Nb 8 O 19 (Nb 16 O 38 ). Natural niobium oxide is known as niobia. Niobium oxidizes in Earth's atmosphere very slowly, hence its application in jewelry as a hypoallergenic alternative to nickel. Niobium oxide (Nb 2 O 5) is a transition metal oxide that exhibits a bandgap value of 3.4 eV. It is used in electrochromic devices, energy-efficient windows, oxygen sensors, and photocatalysis. |
