  Tantalum telluride $(TaTe_2)$ is a chemical compound of tantalum and tellurium. Tantalum also forms a tantalum rich telluride with the approximate formula $Ta_{1.6}Te$ that is unusual in that it forms dodecagonal chalcogenide quasicrystals, a formation that cannot occur in a normal crystal because it does not result in a periodic crystal lattice.
