Web3 jan. 2014 · A final ceramic product had a high flexural strength of 534 MPa. In short, the present gelcasting system is effective for preparing samples with low drying shrinkage and low sintering shrinkage, which is beneficial for controlling deformation or cracking when manufacturing large-sized or complicated parts. Web1 jan. 1989 · A novel method of manufacturing strong Al 2 O 3 bodies with low (<1%) shrinkage is presented. Compacts of attrition-milled Al/Al 2 O 3 powder mixtures are heat treated at temperatures between 1200 and 1550°C such that the expansion due to the Al→Al 2 O 3 reaction and the shrinkage on sintering of Al 2 O 3 is nearly balanced.
