SYNTHESIS OF ALUMINIUM BORATE WHISKERS THROUGH WET MOLTEN SALT METHOD

摘要

Aluminium borate (Al4B2O9) whiskers were successfidly synthesized by the wet molten salt method at 800 degrees C through control the aluminum/boron atomic ratio and synthesis temperature. The as-received Al4B4O9 whiskers were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermal analysis. A solution-liquid-solid(SLS) mechanism was proposed for the growth mechanism of the whiskers on the basis of the experimental phenomena and the TG-DSC data of the mixed raw materials.
