| Abstract: | Experimental evidence for the formation of Ti3B4 with an orthorhombic Ta3B4-type structure is presented. This phase forms by a peritectic reaction between TiB2 and liquid at ∼2200°C and is stable to temperatures at least as low as 1690°C, the lowest temperature at which samples were annealed. No evidence was found to indicate the presence of a second high-temperature form of this phase, as has been reported in the literature. |
