摘要：

In the present study, one-step activation and chemical reduction process as a novel wet-chemical route was performed for the preparation of TiC/W core-shell structured ultra-fine powders. The XRD, FE-SEM, TEM and EDS results demonstrated that the as-synthesized powders are of high purity and uniform with a diameter of approximately 500 nm. It is also found that the TiC nanoparticles were well-encapsulated by W shells. Such a unique process suggests a new method for preparing X/W (X refers the water-insoluble nanoparticles) core-shell nanoparticles with different cores. (C) 2014 Elsevier B.V. All rights reserved.
