%X The phases in different depth of a sample for pulse electric current sintering AlOOH was investigated by means of XRD analysis. The results show that: (1) the phases in top surface are different with that in down surface which indicates that the temperature decrease from top to down in the sample; (2) the peak of XRD in the top surface is lower than that in the next layer(0.3mm to top surface). Comparing the results of microwave plasma bombardment and HP with pulse electric current sintering, it is found that the top surface of SPS sample has similar XRD patterns with that of microwave plasma bombardment sample. So it is deduced that the top surface is bombarded by plasma, thus making the crystal structure distorted. The reason for forming the heterogeneous phase in the sample was analyzed in this paper.
