Nanoparticles of ZnO Doped With Mn: Structural and Morphological Characteristics [PDF]
In this study, the effects of dopant concentrations on the structural and morphological characteristics of Zn1-xMnxO powders (x= 0.025, 0.05, 0.075, and 0.1 mole) synthesized by the Pechini method has been investigated.

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

Characteristics of Samaria-Doped Ceria Prepared by Pechini Method
CeO2 ceramics doped with 20 mol.% samarium (SDC-20) were prepared through the Pechini process. The samples were calcined at 400, 700 and 1000 °C. The sintering behavior of the calcined SDC-20 powders was also investigated at 1400 °C for 6 h. Microstructural and physical properties of SDC-20 samples were characterized with X-ray diffraction, scanning ...
