This paper highlights the process to fabricate alumina microcomponents. It was achieved by firstly sintering Al microcomponents using micro/nanopowders, and then turning Al into alumina (Al2O3) through oxidation. In this way, the shrinkage occurring in sintering the Al powder is compensated by the expansion occurred when Al transforms into alumina. The process has proven successful.
