Deheria, S S (2014) Production of alumina based porous ceramics using graphite powder as the pore former. BTech thesis.
The present work focuses on the production of alumina based porous ceramics and its characterization. Five different alumina samples having different weight % of graphite, between (0 – 25) % were prepared by die pressing. Pellets were fired at different range of temperatures (1450oC –1650oC) with soaking period of 2 hrs. It was found that with increase in the weight percentage (wt %) of graphite, the porosity increases, bi-axial flexural strength decreases. But bi-axial flexural strength increases with the increase in sintering temperature. Bulk density also decreases with increasing in graphite content however the absolute bulk density increases with increasing sintering temperature.
