TmC2

Thulium dicarbide (TmC2) is a rare-earth transition metal carbide ceramic, belonging to the family of refractory carbides used in extreme-temperature and high-hardness applications. While primarily a research material rather than a commodity ceramic, TmC2 is investigated for specialized aerospace and nuclear contexts where its combination of chemical stability, thermal properties, and hardness at elevated temperatures offer potential advantages over more conventional carbides. The material exemplifies the exploration of rare-earth carbides for next-generation thermal protection systems and wear-resistant coatings where conventional alternatives like tungsten carbide or zirconia may fall short.
