Mechanochemical synthesis of NaNbO3

The mechanochemical synthesis of NaNbO3 is studied. It is shown that NaNbO3 can be prepared by milling the constituents, i.e. Na2CO3 and Nb2O5 in the planetary mill. After 40 h of mechanochemical treatment NaNbO3 nanoparticles in the range of 10–20 nm are obtained. Furthermore, the high-energy milling leads to the mechanochemically-triggered carbonate decomposition, which has been observed for a few cases in the open literature.
