Sintering process analyzed mathematically by prediction unsteady-state mathematical model in order to give more description and understanding for the mechanism of this process, which includes mass transport that may occur via diffusion.
The spatial and temporal temperature profile with the solid medium has been determined by solving the unsteady state Fourier heat energy transport equation using the explicit finite difference numerical method, which would minimize the solution errors, this leads to more realistic determination of temperature distribution within the work-piece. Alumina has been selected as target to represent nonmetallic material of diverse physical and thermal properties. The average grain size for alumina is 0.5 ?m with initial compact density 2160 kg/m3. These values gave a reliable approach to calculate the porosity and relative strength.
