Phase Formation During Reactive Sintering of the B4C–SiC–Si(Al) Composite (Review)

Abstract

Phase formation was regarded during the reactive sintering of boron carbide materials in the presence of silicon or aluminum, or silicon-aluminum melts. The inter-phase interaction was investigated, the melting (decomposition) temperatures as well as crystallographic data on the phases in the regarded systems were considered. Methods for reducing the content of Si and Al₄C₃ in the composition of the reactive-sintered material were discussed as these substances negatively affect the physical and chemical properties of the material.
