Ball Milling Of Lithium Niobate parafiamchy.pl

Stable suspensions of iron- or copper-doped lithium niobate nanocrystals in heptane are prepared by high-energy ball milling of iron- and copper-doped bulk crystals for 25 h. The distribution of particle sizes is determined by means of dynamic light scattering with more than 90 of the crystals in the range of 10 25 nm.Lithium niobate: from single crystals to nanocrystals,3was prepared from single crystals by the high-energy ball- milling technique. During milling the material suffered partial reduction that lead to the formation of bipolarons and polarons yielding gray color together with Li 2 O segregation on the open surfaces. Upon high temperature oxidation a LiNb 3 O 8shell was formed.
