An investigation about the mechanical and corrosion properties of cordierite based ceramic composites
One of the essential phases in the MgO-Al2O3-SiO2 (MAS) system, cordierite, has the chemical formula 2MgO• 2 Al2O3 • 5 SiO2. Therefore, cordierite is generally produced from natural raw materials by liquid phase sintering. In this study, dense cordierite and cordierite-based/ZrO2 ceramic composites...

| description | One of the essential phases in the MgO-Al2O3-SiO2 (MAS) system, cordierite, has the chemical formula 2MgO• 2 Al2O3 • 5 SiO2. Therefore, cordierite is generally produced from natural raw materials by liquid phase sintering. In this study, dense cordierite and cordierite-based/ZrO2 ceramic composites were produced economically from natural zeolite at a temperature as low as 1250 °C. Phase analyses with XRD and microstructure examinations with SEM/FESEM were performed. The hot salt corrosion behaviour of ZrSiO4 crystals in a cordierite matrix was also tested. It was determined that the addition of ZrO2 to reduce the average grain size had a positive effect on wear and corrosion resistance. Density, porosity, hardness, flexural strength and wear behaviour of the cordierite-based/ZrO2 ceramic composites were determined. In addition, the hardness values of the zirconia free sample, the samples containing 10 and 20 wt.% zirconia were measured as 11.29, 12.60 and 12.91GPa, respectively, while the specific wear rates were identified as 5.097 × 10−3, 6.302 × 10−6 and 3.393 × 10−7 mm3/Nm, respectively. The hardness increased and the wear resistance changed with the addition of zirconia. |
