Alumina ceramic products were made by die pressing, slip casting and extrusion. The products were tested for various physical properties such as percentage shrinkage, bulk density, apparent porosity, water absorption, scratch hardness and thermal conductivity. Increase in sintering temperature resulted in increase in percentage shrinkage of extruded rods and pressed discs from 6.6 % to 11.3 %. Scratch hardness of the extruded rod sample is around 8.5 whereas hardness values of slip cast sample is around 8 on Mohs scale. A simple method has been developed to obtain porous ceramic for thermal insulation purpose of furnaces upto 1600 oC. Porous block made has thermal conductivity value of 0.33 Wm-1K-1 and the density of 0.7 gm/cm3
