Abstrakt: Abstract: Porous α-Al2O3 ceramics for microfiltration membranes can he obtained by calcination of Al(OH)3 in the temperature interval 1150 - 1400 °C followed by milling and sintering. Calcination at 1150 °C provides θ-Al2O3 whose sintering leads to approx. 8 % higher porosities comparing to α-Al2O3. Milling of calcined powder has significant influence on decreasing of the mean pore size which is accompanied by the 20-25 % decreasing of porosity.
