AB  - Solid state and sacrificial techniques were used to prepare the porous alumina ceramics. The target
of the present resesrach is to investigate the effect of Cu metal addition of nanoscale particle size on the
physical properties of porous alumina ceramics using graphite waste as a pore-forming agent. X-Ray Diffraction
(XRD), a Field Emission Scanning Electron Microscope (FESEM) and a Transmission and Electron Microscope
(TEM) were used to analyse the microstructure and ceramic phases. Different ratios of Cu metal were added (3,
6, 9 and 12 wt.%) at different ratios of graphite waste. The results of this investigation show that with increasing
ratios of Cu metal, the porosity decreased while the shrinkage and densities increased. Increases in the density
and decreases in the porosity of porous alumina ceramics and the formation of the tenorite (CuO) phase due
to sintering at high temperature (1600°C) may lead to improving the strength of porous alumina ceramics. Some
potential applications include gas filtration components and as thermal insulation materials.
