Abstract
In view of discrepancies in the available information on the hardness of li thium niobate, a systematic study of the hardness has been carried out. Mea surements have been made on two pure lithium niobate crystals with differen t growth origins, and a Fe-doped sample. The problem of load variation of h ardness is examined in detail. The true hardness of LiNbO3 is found to be 6 30 +/- 30 kg/mm(2). The Fe-doped crystal has a larger hardness of 750 +/- 5 0 kg/mm(2).
