The invention discloses a technology for preparing zirconium nitride ceramic microspheres and the zirconium nitride ceramic microspheres, wherein the technology comprises the following steps: mixing ZrO(NO3)2*xH2O, hexamethylenetetramine, urea, concentrated HNO3 with carbon black to obtain a glue solution; dispersing the glue solution into hot silicone oil dropwise, solidifying droplets in the silicone oil to obtain gel microspheres; aging the gel microspheres in the hot silicone oil to react the gel microspheres completely; washing the gel microspheres to remove the silicone oil on the surface of the microspheres and residual unreacted materials; drying the washed gel microspheres to obtain dried gel microspheres; subjecting the dried gel microspheres to carbon thermal nitridation treatment, and sintering and densifying simultaneously to obtain the zirconium nitride ceramic microspheres. According the technology, the zirconium nitride ceramic microspheres are produced by combining aninternal gel method with a carbon thermal nitridation method, the obtained zirconium nitride ceramic microspheres are pure phase zirconium nitride, and the microspheres have good sphericity, uniform size, complete structure without cracks, and good mechanical properties.
