Abstract: Based on the uniform experimental design as well as datamining technology results，the rod-like ammonium aluminium carbonate hydroxide was synthesized by solid-state reaction at low temperature，and aluminum borate whiskers were prepared with rod-like ammonium aluminum carbonate and boric acid as raw materials.Experimental results indicated that the Al—O framework of rod-like ammonium aluminium carbonate hydroxide induced the synthesis of aluminum borate whisker， and using KCl as smelter flux was good for one-dimensional whisker′s growth.The product was characterized with X-ray diffraction（XRD） as well as scanning electron microscopy（SEM）.The characterized results indicated that the aluminum borate whisker′s average diameter was 0.4 μm and average length was about 16 μm.

Key words: rod-like ammonium aluminum carbonate hydroxide, aluminum borate whisker, induction, smelter flux
