From: Rapid and direct synthesis of complex perovskite oxides through a highly energetic planetary milling
(a) XRD patterns of the mechanochemically treated stoichiometric K2CO3-Na2CO3-Nb2O5 powder mixtures as a function of the milling time under condition number 2 (ΔEb = 421 mJ/hit, vt = 3825 s−1). (b) TEM bright-field image and selected-area diffraction pattern of the powders mechanochemically treated for 40 min.
