Discover the 2026 Ekeberg Prize-winning research into θ-phase tantalum nitride, a material with thermal conductivity nearly three times that of copper.

Feature Article Title:

Metallic θ-phase Tantalum Nitride Has a Thermal Conductivity Triple That of Copper

Feature Article Summary:

Winner of the 2026 Anders Gustaf Ekeberg Tantalum Prize, this research reports a single-crystalline form of θ-phase tantalum nitride with a measured room-temperature thermal conductivity of approximately 1,100 watts per metre-kelvin, nearly three times that of copper. The research could open new possibilities for thermal management in AI hardware, power electronics and other high-performance technologies. While the material remains at the laboratory demonstration stage, the judging panel highlighted its scientific impact and its potential implications for future tantalum demand and supply chains.
