Niobium(V) ethoxide, also known as Niobium pentaethoxide or NbOEt, is an organoniobium compound with the molecular formula C₁₀H₂₅NbO₅ and a molecular weight of 318.21 g/mol. This compound features niobium in a +5 oxidation state, coordinated with five ethoxide groups, forming a stable molecular structure ideal for chemical reactions involving niobium. Niobium(V) ethoxide appears as a yellow to gold liquid with a purity of 99%, confirmed by gravimetric assay. Due to its high sensitivity to moisture, it requires storage under an inert atmosphere.
Niobium ethoxide is commonly utilized as a niobium precursor in various chemical syntheses and material fabrication. Its reactivity makes it a valuable reagent in producing niobium-based thin films and coatings through sol-gel processes and metal-organic chemical vapor deposition (MOCVD). Additionally, its structure enables controlled hydrolysis reactions, which are essential for creating high-performance niobium oxides and ceramics used in electronics and catalysis.
Classified with hazard codes H226, H314, and H318, Niobium(V) ethoxide is a flammable and corrosive liquid that can cause severe eye and skin irritation. It should be handled with appropriate protective equipment, including gloves, goggles, and flame-resistant clothing, and used in well-ventilated areas. Due to its moisture sensitivity, storage in sealed, moisture-free containers under an inert gas, such as nitrogen or argon, is essential to prevent degradation.
In both industrial and laboratory contexts, Niobium(V) ethoxide plays a crucial role in synthesizing advanced niobium materials and is essential for developing niobium-based ceramics and electronic components. Its use in thin-film deposition, especially in the creation of niobium oxide layers, is highly valued in material science and semiconductor manufacturing. The compound’s unique properties make it indispensable for specialized applications in high-tech industries focused on electronics, catalysis, and advanced material development.
Niobium(V) ethoxide is used for the sol-gel processing of materials containing niobium oxides and mixed metal oxides. It is also used to prepare ferroelectric nanomaterials consisting of oxides of potassium, silicon, and niobium. See links below
