| description | The invention relates to the technical field of synthesis of novel composite ceramic spherical particles, and discloses a preparation method of spherical titanium carbonitride ceramic powder. The preparation method comprises the following steps: weighing Ti powder, graphite powder, deionized water and Arabic gum according to a mass ratio to obtain a slurry suspension; adding a sodium carboxymethyl cellulose dispersing agent, and stirring by a motor to obtain a uniformly mixed slurry solution; the method comprises the following steps: performing high-speed centrifugal spray drying, collecting and sieving to obtain Ti-C agglomerated powder with the particle size of 38-74 microns, synthesizing titanium carbonitride based on a self-propagating reaction of a Ti-C-N2 system in high-temperature plasma flame flow, capturing flying particles in the high-temperature flame flow by utilizing a self-made cooling device, and collecting and drying to obtain the titanium carbonitride spherical particles.
