摘要: Abstract Porous cordierite ceramics were produced from stevensite-rich clay and andalusite mixture using oil shale (OS) as a natural pore-forming agent. The pressed pellets of powdered samples sintered at 1300 °C for 2 h both conventional sintering (CS) three-step (TSS) cycle. mechanical properties evaluated by three-point bending test, Brazilian test ultrasonic measurements. microstructure are strongly influenced the conditions amount added (0–20 wt%). cycle maximum addition resulted in an increase pore size open porosity 17.7% to 52.8%. exhibited higher flexural tensile strengths (25.4 16.8 MPa, respectively) than those via (11.2 7.54 MPa, respectively). However, gradual revealed strong decrease such strength (44.6–17.8 MPa), (19.2–13.3 MPa) Young׳s modulus (70.5–46.8 GPa). formation mechanism porous structures adding also reported discussed.
