The presence of KCuF<small><sub>3<\/sub><\/small> and KNiF<small><sub>3<\/sub><\/small> in the desired crystalline phase as the main product was observed after 6 h of milling. At higher milling times K<small><sub>2<\/sub><\/small>CuF<small><sub>4<\/sub><\/small> and K<small><sub>2<\/sub><\/small>NiF<small><sub>4<\/sub><\/small> were detected as additional crystalline phases for the Cu- and Ni- based perovskites, respectively. The fluorinated perovskites were characterized by using X-Ray Powder Diffraction (XRD), X-Ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM), confirming the selective formation of the fluorinated perovskites. The mechanochemical route was also compared to a new mild solvothermal method. An evaluation of the environmental impact and the energy efficiency was performed; moreover, the effectiveness of the mechanochemical process was compared to that of the solvothermal method. The promising results obtained from this innovative method opened the door to the use of solvent-free mechanochemical syntheses as a suitable approach in the field of crystal engineering also.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author(s): Davide Ceriotti, Piergiorgio Marziani, Federico M.
