In this communication we present our results of the feasibility of sintering greens compacts of metallic powder of MoSi2 by a CO2 laser beam as the heating source. The main advantage of this technique is to promote a dense material in a reduced time when compared to the conventional sin-tering process. In order to sintering the MoSi2 powder, greens compacts of 6mm of diameter and 1.6mm thickness were produced in a stell die in a uniaxial press at 100MPa and after, isostatic pressed at 350MPa. The micrograph of the samples exposed to the laser radiation performed by scanning electron microcopy (SEM) reveal the effciency of the sintering process and the X-ray diffraction of the powders confirmed the presence of single phase after and before laser processing. The average microhardness of these compacts reached near to 700 H?0.2 in the cross section to the laser irradiation, indicating the all sintering of the green copmpact.
