Abstract

Abstract

In this paper,thermodynamic calculation and analysis are carried out for preparation Ti₄O₇.With the help of differential thermal-thermal gravimetric analysis,the technological conditions for preparing Ti₄O₇ with titanium powder as reductant are explored,the sintering temperature is 850 ℃ and the sintering time is 4 ~6 h.Testing and analyzing the thermal stability,XRD,particle size,conductivity and specific surface area of Ti₄O₇.which provided the reference and basis for the preparation of Ti₄O₇.
