Abstract

Ti ₂PbC was synthesized for the first time by pressureless reaction synthesis using Ti/Pb/TiC as starting materials at a heating rate of 2 ℃/min and holding at 1370 ℃ for 2 h in a tube furnace protected by Ar atmosphere. The effects of starting powders, heating rates, and holding temperatures on the formation of Ti ₂PbC were investigated. It was found that elementary mixture of Ti/Pb/C or higher heating rates fail to form Ti ₂PbC. The decreased lattice parameters in the synthesized Ti ₂PbC indicated the existence of Pb vacancies in the compound. A reaction mechanism was proposed to explain the formation of Ti ₂PbC.
