dc.description.abstractIn this study, production of porous ceramic from clinoptilolite incorporating aluminum powder at various sintering temperatures was investigated. The mixtures were sintered at 1150, 1200, 1250 and 1300 °C for 1 h in air atmosphere. SEM and XRD analyzes were conducted to observe the microstructural evolution and the phase composition, respectively. The DSC/TG analyzes of the clinoptilolite and aluminum powder mixture indicated that 1150 °C was a significant temperature at which oxidation of molten aluminum enhanced and the softening of the clinoptilolite began. The progress in oxidation of aluminum with increasing temperature led to corundum phase crystallization while the amount of cristobalite decreased. Aluminum distribution in the ceramic matrix began at 1200 °C but pore channels with very smooth surfaces were obtained at 1250 °C. At this temperature, the pores interconnected to each other had narrow pore size distribution (4–180 μm) with low friction coefficient of 0.64 resulting from enhanced corundum phase formation in the structure. Results showed that the porous ceramic sintered at 1250 °C with 32.8% apparent porosity and a pure water permeability of ~2050 L/(m2•hr•bar) promises great potential for use as a filtering media and/or support. © 2019
