General description
Niobium(V) ethoxide is a colorless liquid that is miscible with some organic solvents, but which hydrolyzes readily. Niobium(V) ethoxide boils at 142 °C at 0.1 mmHg.
Application
Niobium ethoxide is an important precursor for depositing thin films of niobium oxide and other thin films doped with niobium. Because of its low boiling point and low decomposition temperature (~325-350 °C), niobium(V) ethoxide is used as a precursor in atomic-layer deposition (ALD), chemical vapor deposition (CVD), and metal-organic chemical vapor deposition (MOCVD) of niobium oxides.
Features and Benefits
Niobium(V) ethoxide packaged for use in deposition systems is packaged in a SWAGELOK stainless-steel deposition system convenient for connecting to ALD, CVD, and MOCVD systems.
- Steel cylinder connected to 316 stainless steel ball-valve
- 1/4 inch male SWAGELOK VCR connections
