“…Porous materials have been utilized in a broad range of applications for both industrial and daily life sectors [1][2][3][4][5]. Among porous materials, porous ceramics possess many advantages over other porous materials such as polymers or metals, namely high hardness, chemical inertness, thermal shock resistance, corrosion and wear resistance, and low density [4][5][6][7][8][9]. Alumina (Al 2 O 3 ) has been one of the most common materials for applications of porous ceramics such as lters, catalysis, and thermal insulators [10][11][12].…”

Highly porous alumina (Al2O3) was prepared by sintering of Al2O3 powder using ammonia bicarbonate (NH4HCO3) as a pore-forming agent and chromia (Cr2O3) as a sintering additive. In order to investigate the influence of particle shape and size on the characterization of sintered porous Al2O3, the starting Al2O3 powders included commercial disk micro-sized powder and synthesized spherical nanopowder. The nanoscale Al2O3 powder was produced via combustion synthesis route. At the optimal pore-forming agent concentration, the porous Al2O3 sintered by nanoparticles had a smaller pore size and a lower total porosity than the one prepared by microparticles. The differences of open porosity and closed porosity between porous Al2O3 synthesized by micro and nano-scale powders with and without Cr2O3 dopant were also discussed. In addition, the compressive strength of porous Al2O3 achieved by nano-sized powders, especially with Cr2O3 dopant, had a higher value in comparison with the one prepared by micro-sized powders.

“…In recent times, porous ceramics have been prioritized over other inorganic counterparts due to their great potentials to function decently in variety of industrial applications such as filtration membranes, electrodes in fuel cells, catalyst support, thermal insulation systems, bone scaffolds and others . For each individual application, a controlled and homogeneously infused pore network with suitable geometry and morphology are required.…”

This 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 (70-178 lm) 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.
