英文摘要	The exothermal agent KClO3 was added to the B2O3-CeO2-Mg system to prepare the ultra-fine CeB6 powders via salt-assisted combustion synthesis. The products were analyzed by XRD, SEM, EDS and TEM. The formation mechanisms of the CeB6 as well as the effect of compaction pressure on the phase composition, average particle size and purity of the products after leaching were studied. Results show that the main product of combustion synthesis is CeB6. With increasing the compaction pressure, the average particle size of the synthesis products increases slightly after leaching, which is 0.830-0.930 mu m and the particle size distribution of powders is uniform. However, the purity of CeB6 reaches a maximum of 99.0 wt% when the pressure is 20 MPa. The purity of all products under different pressures exceeds 98.0%.
