Abstract
Boron carbide is a highly covalent non-oxide ceramic with a high melting temperature. Therefore, the densification of boron carbide via a thermally activated process is extremely hard and requires additional driving forces. In addition to searching alternative production techniques for boron carbide, the production of boron carbide composites is one of the most interested subjects. In this study, BxC-TiB2-SiC ceramic was produced through an in-situ reaction between B4C and Ti3SiC2 and excess amorphous boron using spark plasma sintering method at 1600°C-1800°C. XRD and microstructure analysis of the sintered sample show that boron rich boron carbide phase is present in the sintered specimen, which did not develop a continuous matrix through the sample. The three phases present in ceramics formed agglomerate throughout the microstructure and did not show homogeneous distribution.
