TEMPERATURE DEPENDENCE OF YOUNG’S MODULUS OF SILICATE CERAMICS FROM THE MAGNESIA–ALUMINA–SILICA SYSTEM
Original language description
Silicate ceramics based on the magnesia-alumina-silica system, including mullite ceramics, steatite ceramics and cordierite ceramics are among the most widely used engineering ceramics. In this contribution the temperature dependence of the Young’s modulus, i.e. a basic input parameters e.g. for thermal shock parameter calculations, is investigated in a systematic way with changing composition, achieved by mixing two raw materials (kaolin and talc). After characterization via X-ray diffraction, thermal analysis and laser diffraction the raw materials were mixed to achieve kaolin-talc weight ratios of 10:0, 8:2, 6:4, 4:6, 2:8 and 0:10, ball-milled in water, dried, crushed, uniaxially pressed at 40 MPa and sintered at 1280 °C (2 °C/min, 2 h). The samples were characterized by X-ray diffraction and Archimedes measurements and their Young’s modulus was measured via impulse excitation, from room temperature up to 1000 °C. The results indicate that all materials contain cristobalite and exhibit its typical elastic anomaly. The elastic hysteresis that is well known for materials containing cordierite is suppressed in materials that contain also mullite beside cordierite. The Young’s modulus of compositions made with kaolin-talc ratios 10:0, 8:2 and 0:10 is almost independent of temperature.
