Mechanochemical synthesis of a La0.67Ce0.21Nd0.08Pr0.04Ni5 intermetallic compound

Advanced Powder Technology, 2013
Abstract The mechanochemical synthesis of a La 0.67 Ce 0.21 Nd 0.08 Pr 0.04 Ni 5 intermetallic is studied. The intermetallic is synthesised from a mixture of LaNi 5 and La 0.25 Ce 0.52 Nd 0.17 Pr 0.06 Ni 5 . The processes controlling the mechanical alloying are characterised as a function of integrated milling time ( t m ). Effects of fracture and

Mechanochemical synthesis of Ba0.8Sr0.2TiO3 [PDF]

, 2011
Ba0.8Sr0.2TiO3 was prepared from the starting materials BaCO3, SrCO3 and TiO2 through solid state reaction. Mixtures of these oxides were mechanically activated using a high-energy ball mill at different time intervals from 0 to 120 minutes. X-ray diffraction was employed in order to determine the crystal structure and gave information about ...
