摘要：TiB2particles are prepared by TiC in Al melts and the characteristics of them are studied. It is found that TiC particles are unstable when boron exists in Al melts with high temperature and will transform to TiB2and Al4C3. Most of the synthesized TiB2particles are regular hexagonal prisms with submicron size. The diameter of the undersurfaces of these prisms is ranging from 200 nm to 1 μm and the height is ranging from 100 nm to 300 nm. It is considered that controlling the transformation from TiC to TiB2is an effective method to prepare small and uniform TiB2particles. © 2011 Elsevier Inc.
