[15P-T17-03] Fabrication of Boron Carbide Composite Material Using Reaction Boronizing Sintering for Thermoelectrics
Keywords:Boron Carbide, SPS
Boron icosahedra cluster compounds possess attractive properties such as high hardness and unique electrical and thermal properties. Boron carbide, one of the boron icosahedra cluster compounds, exhibits attractive thermoelectric properties. However, boron carbide is hard to sinter because of the strong covalent bonding of boron.we focused on the Reaction Boronizing Sintering(RBS) method to sintering boron carbide materials. In RBS, the eutectic liquid phase between metal and boron promotes the densification of the borides. In this study, the effects of metal addition on the thermoelectric properties were investigated. Boron carbide base materials were synthesized by powder metallurgy method using SPS from B, C, and metal powders, Mn, Fe, Co and Ni.
According to XRD measurement of SPSed materials, boron carbide and metal boride, MB or MB2, were appeared.
The metal addition effect on the microstructure and the detailed thermoelectric properties will be discussed on the day.
