Abstract

Abstract

Nano titanium carbide (TiC) powder was synthesized by detonation shock utilizing octogen (HMX) as high temperature and high pressure source with titanium dioxide (TiO₂) and activated carbon (C) as precursors. The samples were characterized by X-ray diffraction (XRD), energy dispersive spectrometer (EDS) and scanning electron microscope (SEM). At the same time, detonation shock synthesis mechanism of nanometer TiC was discussed in this paper. It was concluded that the test results of XRD and EDS were in good agreement with the theoretical values, and the sample contained both TiC and TiC_x (x＜1). The particle size of both TiC and TiC_x (x＜1) were less than 50 nm by SEM photos and micron-sized spherical agglomerates were found in the samples. The detonation shock synthesis of TiC belongs to a special solid-phase reaction, and its material diffusion rate and reaction rate are greatly improved.
