Microstructure of Al₂O₃+Cordierite+AlN Composite Ceramics

Abstract:

Aiming at the preparation problems of Al₂O₃+cordierite+AlN composite ceramic, the experiment emphatically investigates two influencing factors both the addition of cordierite and Al₂O₃ and sintering process parameter. The Al₂O₃+cordierite+AlNcomposite ceramic has been obtained through such technique procedure as mixing materials, ball-milling, forming by dry pressing and pressutrless sintering in nitrogen at temperature between 1350°C~1400°C. The chemical compositions of ceramic are examined by XRD diffraction. The microstructure and composition of the fracture of the materials are observed by SEM and EDS. The results show that owing to the addition of cordierite the composite ceramic has been sintered at 1375°C;the composite ceramic are more dense sintering at higher temperature; more Al₅O₆N can be obtained by improving the content of AlN, thus improving the thermal conductivity.
