Abstract

Recent referential studies on combustion synthesis of titania nanoparticles were briefly reviewed. Computations based on the minimization of Gibbs free energy were conducted to find the equilibrium compositions, the optimal reaction temperature, the suitable mole ratio of oxygen to titanium tetrachloride, and the best inlet positions of titanium tetrachloride. The mean particle diameter was obtained from particle-dynamic simulation. A combustion apparatus was setup to synthesize titania nanoparticles by the oxidation and hydrolysis of titanium tetrachloride at high temperatures. Experimental investigation verified some results obtained from thermodynamic and particle-dynamic computations.
