Bulk crystals of RETiNbO6 (RE = Nd, Pr) with size φ 15 × 20 mm have been grown by a modified Czochralski method. The RETiNbO6 compounds melt incongruently and the crystals can only be grown from melts containing a small amount of extra TiO2. The structures of bulk crystals were confirmed by X-ray powder diffraction to be the same as mini-crystals grown by the laser heated pedestal growth (LHPG) method. The bulk crystals were characterized by measurement of their optical absorption and photoluminescence spectra.
