Research output: Chapter in Book/Report/Conference proceedingChapter


Tantalum nitrides (TaNx) nanoparticles with different crystal phase and various morphology were synthesized through low temperature homogenous sodium reduction route with the subsequent assistance of heat-treatment process. X-ray diffraction and TEM results demonstrated that the tantalum nitrides had the morphology of sphere, rectangle or square with the average particle size below lOOnm. The specific surface area of the tantalum nitrides powders measured by BET was around 9.87-13.49m2.g-1, which indicated such nano-sized tantalum nitrides are the promising candidate for capacitor with high specific capacitance.
