Physical Properties Study on Ti-C/NanoCeramics Composite

Abstract

The effect of introducing Al2O3 and CuO nano particles on thephysical properties of sintered Ti-C based materials has been studied.Titanium and carbon elemental powders have been mixed with nanoparticlesof Al2O3 and CuO to produce composites of Ti-C/ceramics at 1100 °C. TheXRD results show that for different amount of mixed nanoparticles, TiC, TiO2,and some rest of the reacted powders are the most dominant stable phases. Interms of physical properties, the results show that the raised Al2O3 percentageleads to gradually increase in apparent density of the sintered mixture ascompared with the purely prepared TiC. Moreover, porosity and waterabsorption decrease with increasing Al2O3 percentage. On the other side,adding CuO to the sintered mixture causes in decreasing the apparent density.Furthermore, it was observed that CuO creates much porosity and increasewater absorption of the sintered mixture.
