Abstract

Abstract: In this work, bulk sapphire crystal has been growth by the flame fusion technique (FFT) and investigated their physical, structural and optical properties. The crystal structure of growth sapphire was studied by X-Rays Diffractometer (XRD) and found to be Al2 O3 structure. The density, refractive index and hardness of growth sapphire were measured and show the values of these parameters are in the range of natural sapphire material. The optical spectrum was measured and optical bandgap was extrapolated and compared with natural sapphire material.
