As an important application of laser rapid forming,the laser bending technology of brittle materials has broad prospects. In this paper,the experiments on bending of Al2O3 ceramic slices with a CO2 CW-laser are carried out at various laser processing parameters, including laser powers and scanning velocities. Laser linear energy density is introduced to explore the best processing parameters for laser bending, and bending characteristics are briefly analyzed according to the high temperature properties of Al2O3 ceramic. Experimental results show that,to realize laser bending for brittle Al2O3 at a temperature gradient,the sample surface must be heated to a specified temperature to ruduce its brittleness and yield stress and to avoid generating cracks. Moreover, the Al2O3 ceramic slice can be bent by the CO2 CW-laser, and the bending angle can be as high as 2° . Furthermore, the laser bending processing of Al2O3 ceramic slice is strongly sensitive to temperature，and there exists a critical temperature, above which, the bending angle increases greatly. The best range of laser linear energy density for bending Al2O3 ceramic is 17～24 J/mm.
