Abstract	In order to get a homogenous mixture and compact of TiB$_{2}$-Al$_{2}$O$_{3}$, hybridization as a surface modification method was used to prepare nano-scale Al$_{2}$O$_{3}$ coated TiB$_{2}$ particles. PE-wax particles were first coated onto TiB$_{2}$ particles by hybridization, and then the nano-scale Al$_{2}$O$_{3}$ particles were coated onto the surface of TiB$_{2}$ coated by PE-wax particles again. SEM, TEM and EDS were used to characterize the microstructure of as-received core/shell particles and its compacts. The experimental results show that a particle-scale homogenous dispersion of TiB$_{2}$ and Al$_{2}$O$_{3}$ can be formed not only in mixed powder but also in dewaxed compacts. The compacts then were sintered by gas-pressing sintering (GPS). Finial products show improved mechanic properties comparing with reference samples fabricated by normal ways.
