Synthesis and Characterization of Nanosized Ti₃O₅ Crystals under Inert Gas Flow

Abstract

In the research, we show that suboxidic Ti7O13 and rutile TiO2 phases formed in addition to the general Ti3O5 phase when the sintering temperature was set at constant argon gas flow rate. Suboxidic Ti7O13 and rutile TiO2 phases were removed by tuning the flow rate of argon gas at constant sintering temperature. At the 1300°C temperature, the smallest Ti3O5 nanocrystals with a size of ~9 nm were produced. Flat shaped particles of Ti3O5 crystals were observed in SEM measurements.

Synthesis of heat storage ceramic λ-Ti3O5 using titanium chloride as the starting material

“…18,[20][21][22][23][24][25] Another approach uses titanium chloride as the Ti source, employing the sol-gel process to produce l-Ti 3 O 5 nanoparticles within a silica matrix. 20,[26][27][28] Additionally, carbon thermal reduction, [29][30][31][32] electrochemical methods, 33,34 and pulse laser deposition (PLD) 35,36 are other notable synthesis methods.…”
