摘要：

New compounds of the compositions Ba(3)Ln(BO3)(3), Ln = La-Lu, Y were obtained in the ternary systems BaO-Ln(2)O(3)B(2)O(3). Single crystals were grown for Ba3Yb(BO3)(3). X-ray diffraction analysis showed a hexagonal structure with space group P6(3)cm and lattice parameters a = 9.411(1), c = 17.481(5) Angstrom, Z = 6, The compounds with Ln = Dy-Lu, Y also crystallize in the space group P6(3)cm. New temperature data on melting points and unit-cell dimensions were obtained for each compound, The berates with Ln = La-Tb are isostructural and crystallize in the space group R (3) over bar, Optical second harmonic generation (SHG) measurements of laser radiation showed that Ba3Yb(BO3)(3) has type I phase transition. By investigation of the crystals of the double berate Ba3Yb(BO3)(3) it was established that the compound possesses a pyroelectric effect. (C) 1999 Academic Press.
