Facile and scalable synthesis of Ti5Si3 nanoparticles via solid-state route in an autoclave

Abstract

A novel method of the synthesis of titanium silicide nanoparticles via solid-state route in an autoclave at 700°C is reported. The reaction of titanium silicide could be described briefly as: 5TiO₂ + 3Si + 20Li = Ti₅Si₃ + 10Li₂O. XRD pattern indicated that the product was hexagonal Ti₅Si₃. The Ti₅Si₃particle size (about 20–40 nm) is confirmed by the TEM images. Furthermore, the thermal stability and oxidation resistance of the titanium silicide nanoparticles were also investigated.
