Rapid synthesis and consolidation of nanostructured Mg 2 SiO 4 –MgSiO 3 composites by high frequency induction heated sintering

Rapid synthesis and sintering of nanostructured MgSiO 3 –Mg 2 SiO 4 composites was investigated via a high-frequency induction heating sintering process. The advantage of this process is that it enables very quick densification to near theoretical density and prohibition of grain growth in nanostructured materials. High-density nanostructured MgSiO 3 –Mg 2 SiO 4 composites were produced by simultaneous application of 80 MPa pressure under an induced output power of 15 kW within 2 min. The grain sizes and hardness of MgSiO 3 –Mg 2 SiO 4 composites were investigated.
