N2 - We grew a Al 25% substituted Ca3NbGa3Si2O14, Ca3Nb(Ga0.75Al0.25)3Si2O14 (CNGAS) bulk single crystal with a diameter of 1 inch by Czochralski (Cz) method. Cracks in the crystal were dramatically decreased by the optimization of temperature gradient. Result of powder X-ray measurement indicated the grown CNGAS bulk single crystal was a single phase of langasite-type phase and lattice parameters, a- and c-axes lengths, decreased by the Al substitution. X-ray rocking curve of polished CNGS specimen indicated the grown CNGS bulk single crystal had great crystallinity.
