Abstract
The porous permeable materials were obtained out of the electro-cast porcelain-bonding corundum with the degree of dispersion 2‒3 and 0,5 mm. The ratios of the 2‒3 and 0,5 mm fractions in the aggregate were 0/95, 35/60, 40/55, 45/50, 50/45, and 95/0. The samples were compacted at the pressure 25, 50, and 100 MPa and burned at 1350 and 1450 °C. The sintered samples had ultimate bending strength from 1,9 to 15,3 MPa, the open porosity from 17 to 26 %, the gas permeability factor for the uniform compositions 1,19 to 3,27 mcm2, those for the two-fraction ones from 0,21 to 3,01 mcm2. The produced porous permeable ceramics is very promising for the application in the way of filters and support films of ceramic membranes. Ill. 3. Ref. 10.
