dc.description.abstractThis study demonstrates a simple and economically viable approach to fabricate porous alumina ceramics shaped with low-priced natural organic pore-forming agents (PFAs) from rice husk (RH) and sugarcane bagasse (SCB) of various weight contents using the powder metallurgy method. Experimental findings revealed that the total porosity (44-67vol%) and average pore size (70-178m) maintained a linear relationship with rising PFA inclusion. Using the diametral compression test, the mechanical response of porous alumina samples was evaluated as a function of porosity and pore geometry. From the overall mechanical strength characterization, the susceptivity of strength on porosity became well marked as the agro-waste shaped porous ceramics exhibited hardness, tensile strength, and elastic modulus of 529.1-26HV, 20.4-1.5MPa and 1662-57MPa, respectively. Moreover, the fractography of the RH and SCB graded porous alumina samples was evaluated as a function of the respective microstructural features. With a plausible tradeoff between pore interconnectivity and mechanical strength, recommended areas of application include solid oxide fuel cells (SOFCs) design, filtration, and thermal insulation systems.en_US
