Ball-milling assisted solid-state reaction synthesis of ...

Mesoporous Li 4 Ti 5 O 12 is prepared via ball-milling assisted solid-state reaction with titanyl sulfate and LiOH as precursors. Different from previous reports, the solid-state reaction route generates mesopores in Li 4 Ti 5 O 12 by removing the impurities after the high-temperature synthesis process.

Solid-state synthesis reaction between Al and Cu powders ...

The solid-state synthesis reaction between Al and Cu during high energy ball milling has been studied. The most important effect of ball milling is that the grain size of the constituents decreased to the nanometer range and the constituents dissolved at the nanograin boundaries. This provides feasible conditions for the solid state synthesis ...

Optimized solid-state synthesis of LiFePO 4 cathode ...

Olivine-type LiFePO 4 cathode materials were synthesized by a solid-state reaction method and ball-milling. The ball-milling time, heating time and heating temperature are optimized. A heating temperature higher than 700 °C resulted in the appearance of impurity phase Fe 2 P and growth of large particle, which was shown by high resolution X-ray diffraction and field emission …
