A comparative analysis of the thermal conductivity for porous alumina using Taguchi
method has been reported in the current research. Porous alumina is one of the most critical ceramics
amongst those that are widely used in the thermal insulator industry; this is because of their physical
properties. Thus, the investigation of these properties is highly desirable. Test variables were
performed for the thermal conductivity studies-weight per cent of a pore-forming agent (yeast),
sintering temperature, and soaking time. Through implementing the experimental design using the
Taguchi method for thermal conductivity of porous alumina was statistically analyzed. The Signalto-
noise ratio and variance analysis investigated the influence of different parameters on the porous
media s thermal conductivity. The result of research determines that the addition of the pore-forming
agent obtained a higher thermal insulator. Based on the optimum conditions obtained from the
Taguchi method factor was 20wt.% weight of yeast cell , sintering temperature at 1200 C , and the
holding time 1.5 h. that give higher value of the S/N ratio.
