LiNb03 crystals have been grown from various melt compositions and with a Mg0 doping up to 9 mol%. For the first time the Li:Nb ratio was estimated by chemical analysis of the Li content in the grown crystals. Doping with Mg0 leads to a decrease of the Li20 content with higher Mg0 content. The Curie temperature was measured for doped and undoped crystals.
