The compound TiB2 has numerous exceptional properties including high hardness, high melting temperature, high electrical conductivity, and nonreactivity with various liquid metals. These make it an attractive candidate for technological applications, such as cutting tools, valve trim for erosive environments, and cathodes in Hall-Heroult cells for aluminum smelting. In general, such applications require fabrication of TiB2 into various shapes, and the latter requirement dictates the production of high-density polycrystalline ceramic bodies. The preparation and characterization of TiB2-based materials have already been the subject of numerous previous works, exemplified by the references (1–9). These include data on the phase equilibria in TiB2 containing systems,1,3,9 the wettability of TiB2 by various metals,1,3,4 and the results of property determinations on TiB2-based specimens.
