英文摘要	The diluent NaCl was added into the W-B2O3-Mg system to prepare submicron tungsten boride powders via salt-assisted combustion synthesis. The products were analyzed by XRD, SEM and EDS, and the effect of NaCl content on phase composition, morphology and average particle size of the products were studied. Results show that the combustion synthesis products before leaching mainly consist of B2O3 and MgO, and the morphology of particles is similar to ellipsoid when without adding NaCl. After adding NaCl, combustion synthesis products before leaching mainly consist of B2O3, MgO, WB and B, and the morphology of particles is irregular and particles are of slight reunion together. The products after leaching are composed of small sized tungsten boride particles; the average grain size decreases with the increasing of NaCl contents; when the content of NaCl k=20, the smallest particle size is 0.85 mu m. The purity of products after leaching is higher, and the contents of W and B are up to more than 98%. The biggest content value of W and B is 98.51% when the content of NaCl k=5%.
