【 摘 要 】

In this paper, the possibility of production of Feâ€�?�TiC nanocomposite as a useful ceramic, from ilmenite concentrate, aluminum powder and carbon black has been investigated. Different amounts of FeTiO₃, carbon black and Al powder were activated by a high-energy ball mill. Then the mixtures were synthesized by microwave heating at various times. The results of XRD investigation indicated that TiC has been synthesized within 5â€�??10 min treatment microwave time. Moreover, it was found that by increasing the aluminum content, the Fe₂O₃ phase was replaced by SiC and Al₂O₃. In addition, from the broadening of the diffraction lines in the XRD patterns analysis, it was concluded that the TiC crystallites are nano-sized. Also, it was found that the existence of Al lead to increased grain size and decrease of the strain in the process.
