Synthesis and Structural Properties of Niobium Pentoxide Powders: A Comparative Study of the Growth Process [PDF]
Powders Nb2 O5 were prepared by two different synthesis method, Sol-Gel and polymeric precursors (Pechini). In the Pechini method before adding the citric acid in the process, four different solutions were used to get the samples. For Sol-gel method, two
