Abstract
High-energy ball milling process has been applied to MgO and Al2O3system. The reaction of MgO and Al2O3is significantly enhanced by the high-energy ball milling process. MgAl2O4spinel phase with an average grain size of about 100 nm is formed at 900 °C from the mixture of MgO and Al2O3after milling for 12 h. Dense MgAl2O4ceramics with 98% of the theoretical density and grain size of 2-5 μm can be obtained by sintering the milled mixture at 1550 °C for 2 h.
