Patent ID: 10486981

Abstract:
The present invention provides a method for producing substoichiometric titanium oxide fine particles, in which the degree of oxidation/reduction of substoichiometric titanium oxide fine particles can be adjusted and which can produce high purity nano-sized substoichiometric titanium oxide fine particles by dispersing substoichiometric titanium oxide (TiOx) fine particles, and especially titanium dioxide (TiO2), in a liquid substance containing a carbon source, adding water so as to form a slurry, forming the slurry into liquid droplets, supplying the liquid droplets to a hot plasma flame that does not contain oxygen, reacting titanium dioxide with carbon in a substance generated by the hot plasma flame so as to produce substoichiometric titanium oxide, and rapidly cooling the produced substoichiometric titanium oxide so as to produce substoichiometric titanium oxide fine particles.
