| Résumé | Lebeau and Figueras introduced the use of liquid metals as media for the synthesis of compounds. The process consists of promoting the reaction of elements by dissolving them in a metallic liquid. One method, known as the auxiliary metal bath process, or the Menstruum process, is used for the production of hard metals. Similarly, mixed carbides of WC, TiC and TaC are produced according to the so-called McKenna process. It is also possible to make silicides, nitrides, carbonitrides and some borides by the auxiliary metal bath process. However, little information is available on the production of TiB2 in auxiliary metal bath, and the present work was undertaken to study its formation in an iron bath. The metallic baths were formed by melting mixtures of ferroboron and ferrotitanium powders. A characterization of the reaction products with respect to the composition of the metallic bath and the temperature of formation is presented. |
