3 was 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 8 shell was formed.
