Abstract
Nanopowders of MgO, Al2O3 and SiO2 were made by high energy ball milling. The simultaneous synthesis and consolidation of nanostuctured MgSiO3–Mg3Al2Si3O12 composites from milled 4MgO, Al2O3 and 4SiO2 powders was investigated by the high-frequency induction heated sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and inhibition of grain growth. Highly dense nanostructured MgSiO3–Mg3Al2Si3O12 composites were produced with a simultaneous application of 80 MPa pressure and an induced current within 1 min. The microstructure, sintering behavior and mechanical properties of MgSiO3–Mg3Al2Si3O12 composite were evaluated.
