Abstract
The rapid sintering of nanostuctured MgO materials in a short time was investigated with a high-frequency induction heating sintering process. A dense nanostructured MgO material with a relative density of up to 99.8% was produced with simultaneous application of 80 MPa pressure and an induced current of with an output of total power capacity (15 kW) within 2 minutes. The effect of the ball milling time on the sintering behavior, grain size and mechanical properties of binderless MgO was investigated. The grain size of sintered MgO decreased with an increase in the milling time. Also the Vickers hardnesses of the MgO with ball milling for 0, 1, 4 and 10 h were 362, 412, 536 and 654 kg/㎟, respectively.
