ABSTRACT

Studied permeable materials obtained by selection of the grain compositions filled with electrofusion corun-dum (EFC) (0.5 mm) and a binder of porcelain (PFL-1). Formulations with different filler / binder ratios were studied, by weight: 99/1, 97/3, 95/5, 93/7 and 90/10. Samples in the form of cross members 40x7x5.5 mm and disks with a diameter of 20 mm and a thickness of 5.5 mm were pressed at a pressing pressure of 25 and 50 MPa and fired at 1350 and 1450 ° C. The flexural strength of sintered samples of all compositions was from 1.1 to 9.8 MPa, the open porosity - from 22 to 33%, and the gas permeability coefficient - from 1.53 to 4.33 μm2. Samples are promising for filters and substrates of ceramic membranes.
