Currently, research focuses on traditional ceramic raw materials that are economical for membrane production. This study investigates the microstructural effects of adding zeolite and periclase to quartz raw materials of varying grain sizes on the transformation of quartz to cristobalite, as well as the changes in porosity and distribution that occur during cristobalite production. For this purpose, structures obtained from quartz (60 wt%)-zeolite (20 wt%)-periclase (20 wt%) mixture powders were separately ground in a ball mill for 6 h as wet grinding and then dried. Each ceramic powder was separated into -125+75, -75+45, -45+20, and -20 μm grain size ranges. After being shaped under 100 MPa pressure, they were sintered at 1100, 1150, and 1200°C. Mineralogical analysis, microstructural development, pore size distribution, adsorption isotherms, and mechanical behavior were investigated. The influence of grain size and sintering temperature on the formation of cristobalite, pore size distribution, and pore volume in porous ceramics was examined independently of composition. The sample passing through the -20 µm sieve and sintered at 1150 °C exhibited the highest adsorption volume of 0.89 P/P₀ at high pressure, corresponding to 0.39 cm³/g, compared to samples sieved through other aperture sizes. This sample also demonstrated the greatest strength, measuring 28.10 MPa.
