英文摘要	Submicron ZrB2 powders were prepared by combustion synthesis using NaCl as the diluent and B2O3, Mg and ZrO2 as raw materials. The samples were analyzed by SEM, EDS, XRD and particle size analyzer. The results show that adiabatic temperature of the system decreases with the diluent content increase. The products are aggregates which contain a small amount of larger-sized particles and a large number of small-sized particles. The average particle size of products drops from 305 nm to 160 nm as the value of k, i.e. molar ratio of the diluent, increases from 0.5 to 1.5. The products after leaching mainly consist of ZrB2 and ZrO2, and the content of the latter decreases with the increase of k. NaCl plays very important roles, such as providing a liquid medium, promoting the mass transfer, improving the purity of the products, reducing the combustion temperature of the system, inhibiting growth of particles by giving a coating on the surface, and leading to small-sized particles.
