Abstract

The goal is to contribute towards well understanding the solid state reaction between Ti-C base ceramic and nano additives. A mixture of elemental powders of Ti and Graphite doped with a range of ceramic nano additives of each Al2O3 and CuO was pressed and heated up to 1100 °C. Phase evolution was then investigated using X-ray diffraction (XRD) and Differential thermal analysis (DTA). TiC is identified to be the most dominant phase through the reaction between Ti and Graphite at 1100 °C. TiO2 is the most detected oxide due to the reaction of Ti-C/ nano Al2O3 and also for Ti-C/ nano CuO reaction. No evidence of both elemental Al and Cu was found due to structural analysis in the final products. On the other hand, energy dispersive X-ray spectroscopy (EDS) results confirm the appearance of Al and Cu in the produced microstructure. Further investigation may generate belief that Al and Cu ingress within TiC structure causing a fluctuation in its measured lattice constant.
