Porous Al2O3 ceramics were sintered by using plasma-chemical synthesized powders with specific surface area values of 30 and 50 m2/g. The sintering was carried out under various conditions: in nitrogen atmosphere, - air or vacuum in the temperature range of 1200 – 1700 °C. The most suitable sintering conditions to obtain porous ceramics are sintering in air in the temperature range of 1200-1500 °C using Al2O3 nanopowder with a specific surface area of 50 m2/g. Samples with open porosity of 35-45% and average pore size range of 110-180 nm were obtained under these conditions.
