Abstract
The preparation of porous alumina ceramics-reinforced begins with the use of (Cu) metal in nanoscale particles as a strengthening phase. At the same time, the solid state and sacrificial techniques are used for the preparation of this porous alumina ceramics-reinforced. Meanwhile, FESEM used to examine the microstructure. The main goal of this research study is to determine the effects of the (Cu) metal in nanoscale particles on the mechanical properties and porosity of porous alumina ceramics. Cu metal added to different ratios of graphite waste as a pore agent. The initial ratio of (Cu) metal added was at 3 wt.%. And this ratio was increased to 6, 9 and 12 wt.% Cu. The results of this study indicate that with an increase in the ratios of (Cu) metal, the porosity shows a decrease while the mechanical properties show an increase. The observed increase in the mechanical properties could be attributed to not only a decrease in the porosity but also to the toughening mechanism of porous alumina ceramics. The areas of potential applications for this type of ceramics include, filtration, thermal and the purging of gas.
