Study of Pressing and Sintering of Gd2HfO5 Powder Obtained by Mechanochemical Synthesis

Gadolinium hafnate (Gd2HfO5) powders are obtained by mechanochemical synthesis from hafnium and gadolinium oxides. XRD, chemical analysis, and scanning and transmission electron microscopy show the transition of initial oxides into single-phase nanodisperse gadolinium hafnate after 30 min of mechanochemical synthesis. This powder is studied for its compactibility and sintering.

Automated summary

The properties of gadolinium hafnate powders prepared by mechanochemical synthesis, including their crystalline state and morphological features, were studied. The results showed that after 30 minutes, gadolinium hafnate powder can form a single-phase nano-dispersed structure.
