中文摘要	The surface characteristics and aqueous dispersibility of commercial silicon nitride powders strongly depend on their specific production methods and post-treatment process. Four representatives of commercial silicon nitride powders were studied in this investigation. Based on measuring the rheological properties, the species of surface atom groups and the oxygen content on powder surface, the effects of powder surface modifications (such as hydrolysis and thermal oxidation) on surface characteristics and aqueous dispersibility were studied systematically. The factors which decrease the powders' dispersibility has been put forward and a universal surface modification method is to be developed to make different commercial silicon nitride powders acquire the similar excellent aqueous dispersibility.
