Porous permeable materials are prepared by selecting the grain size composition with electromelted corundum filler and porcelain mix PFL-1 binder. Specimens with an improved set of properties are prepared with addition to the composition of 5 wt.% porcelain binder (above 100% filler) after firing at 1450°C. Specimen ultimate strength in bending is 14.6 MPa, open porosity 44%, and gas permeability coefficient 0.85 μm
