AB  - Porozna keramika sa industrijskog aspekta predstavlja značajan materijal, međutim, za njenu pripremu se još uvek traže ekonomski i tehnološki prihvatljiva rešenja. Kontrola poroznosti predstavlja ključan korak u postizanju željenih svojstava za određenu primenu. U cilju dobijanja multiporozne keramike u ovom radu korišćena je kaolinska glina i polistirenske perle kao organska žrtvena faza. Uzorci su nakon mešanja sinterovani na 1050 oC tokom 1 h. Karakterizacija je obuhvatila infracrvenu spektroskopiju sa Furijeovom transformacijom (FTIR), 
 kenirajuću elektronsku mikroskopiju (SEM), rendgensku difrakcionu analizu (XRPD), elementnu CHNS analizu i ispitivanje pritisne čvrstoće. Analiza dobijenih rezultata pokazala je da se hijerarhijski uređena, multiporozna keramika, odgovarajućih mehaničkih svojstava može pripremiti u prisustvu organske komponente čijim sagorevanjem tokom sinterovanja zaostaju pore različitih dimenzija.
AB  - From an industrial point of view, porous ceramics represent an important material, however, economically and technologically acceptable solutions are still being sought for its preparation. Porosity control is a key step in achieving the desired properties for a specific application. In order to obtain multiporous ceramics, in this work, kaolin clay and polystyrene beads were used as organic sacrificial phase. After mixing, the samples were sintered at 1050 oC for 1 h. Characterization included Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction analysis (XRPD), elemental CHNS analysis and compressive strength investigations. The analysis of the obtained results showed that hierarchically ordered, multiporous ceramics, with appropriate mechanical properties can be prepared in the presence of an organic component whose burnout during sintering leaves behind pores of different dimensions.

AB  - The aim of this study was to investigate a possibility of synthesis of porous ceramics with controlled open porosity, which could be used as sorbents and catalyst supports. Two organic additives were used to obtain open porosity: polystyrene beads and cellulose fibers, which are mixed with kaolin clay powder and the appropriate water content. Samples were sintered at 1050 oC for 1 h. Characterization of the obtained products included X-ray powder diffraction analysis (XRPD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and elemental CHNS analysis. In addition, porosity was examined by quantification of visual information. The specific surface areas were determined by the Brunauer–Emmett–Teller (BET) method. Also, density and compressive strength of the obtained samples were assessed. It was determined that by sintering, the organic component completely leaves the system. For samples prepared with polystyrene beads and with cellulose fibers, satisfactory mechanical properties were obtained: compressive strengths were 1.42 and 1.56 MPa, respectively. It was noted that significantly higher open porosity was obtained by using polystyrene beads as a sacrificial template (porosity of ̴56 %) instead of cellulose fibers (porosity of ̴6 %).
