Phase equilibria in the Hf+B+C system were calculated by thermodynamic modeling. The liquid phase was described as a substitutional solution using the Redlich+Kister formalism for the excess Gibbs energy and a reaction scheme was constructed for the entire ternary system. With respect to the increasing technological interest in dense ceramic parts Hf B 2 +99B 4 C:: with various degrees of 10 B/ 11 B enrichment as nuclear reactor control or moderator substances, we focus in this paper on the phase relations pertinent to the fabrication of Hf B 2 +99B 4 C:: ceramic material.

The phase diagram of the ternary Ti-B-C system has been constructed from 300 to 3500 K, especially for the sections TiC y -TiB 2 and B 4 C y -TiB 2 . The calculation of the energy parameters describing the phase equilibria with the participation of TiB 2 has been carried out in the subregular soluti
A new rare earth boron-rich compound was found in the Y-B-Si ternary system. The powders were synthesized by solid state reaction method and single crystals were grown by the high temperature solution method with silicon flux. The structure was solved from single crystal x-ray diffraction data with
