Abstract
Different methods are described for preparing borides and boron carbide by powder technology. The boron carbide was prepared from amorphous boron, graphite, and petroleum coke, and the borides from amorphous boron and atomized aluminium. The compounds are characterized and compared with their commercial counterparts. In the second part of the work, cheaper materials are used: boric acid and boric oxide instead of boron, petroleum coke and mesophse instead of graphite. Another alternative studied in this work is the use of thermal shock in the sintering, a method that is not usually adopted in powder technology.
