Abstract: | Single crystals of tricalciumborate were grown by the flux method. Ca3B2O6 crystallizes in the rhombohedral system with the unit cell parameters , αR = 85.68(8)°, Z = 2. The equivalent hexagonal lattice parameters are aH = 8.640(1), . The anisotropic thermal expansion parameters αa = (1.00 ± 0.14) × 10?5, αc = (3.60 ± 0.47) × 10?5 were determined by X-ray methods in the temperature interval 25 – 1000°C. |
