Sinterability of SiB₆-B₄C ceramics

Abstract

Silicon boride (SiB₆) was reported that have the characteristics of oxidization resistance and excellent hardness in the high temperature. On the other hand, Boron carbide (B₄C) was known that have high hardness after the diamond, and high See-beck coefficient. It is able to expect that the SiB₆-B₄C composite ceramics have the characteristics of hardness, resistance oxidization, and high See-beck coefficient in the high temperature. SiB₆-B₄C ceramics were prepared by hot-press sintering method. The sintered body's chemical components were determined by using X-ray diffraction analysis and their relative density and electrical conductivity were measured.
