摘要：

Ca3LixNb(1.5+x)Ga-(3.5-2x)O-12 garnets were synthesized and the conditions of the crystal growth are established. The measured lattice constants are about 12.54 Angstrom irrespective of x. It was found that the Ca3Li0.275Nb1.775Ga2.95O12 garnet melts congruently at about 1450 degrees C. Transparent and bubble-free crystals of x = 0.25 and 0.275 were grown by both modified micro-pulling down and Czochralski techniques in air using Pt crucibles. Results of solid state reaction data of other garnets are also discussed. An absorption spectrum is also reported.
