Abstract


In this work, preceramic papers containing 85 wt% Al2O3 were heat-treated at 1600 °C to obtain paper-derived ceramics. In order to increase the preceramic paper density prior to sintering, the papers were calendered at different roll temperatures and pressures. The influences of the calendering parameters on the microstructure and mechanical properties of the preceramic papers and the paper-derived ceramics were investigated. It was expected that especially the mechanical properties of the papers and derived ceramics would be improved by calendering.



The increase in the preceramic paper density led to an increase by 85 % of the green tensile strength from 20 MPa to 37 MPa in cross direction (CD) and by 91 %, from 11 MPa to  21 MPa in machining direction (MD). An increase in flexural strength by  96 %, from 138 MPa to 270 MPa, was obtained for the paper-derived ceramics with an increase in density by 25 %, from 2.4 g/cm³ to 3.0 g/cm³, and the shrinkage after sintering was reduced from 15 % to 12 % owing to the previous calendering of the preceramic paper.
