Abstract
Disclosed herein is a method for preparing ultrafine titanium carbonitride powder under a relatively low temperature condition that obviates a grinding process. This method includes the steps of: a mixing step for contacting titanium dioxide (TiO2), calcium (Ca) and carbon (C) under an inert atmosphere, a synthesis step for reacting the resultant mixture by heating at a temperature of about 600-1500° C. or lower under a nitrogen atmosphere; and a washing step for removing calcium oxide by washing this mixture.
