一般描述

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.

应用

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.

特点和优势

Niobium(V)ethoxide packaged for use in deposition systems is packaged in a Swagelokstainless-steel deposition system convenient for connecting to ALD, CVD, andMOCVD systems.

  • Steel cylinder connected to 316stainless steel ball-valve
  • 1/4 inch male Swagelok VCRconnections
