Recognising excellence in tantalum research and innovation
The Anders Gustaf Ekeberg Tantalum Prize (‘Prize’) is awarded annually for outstanding contribution to the advancement of the knowledge and understanding of the element tantalum (Ta).
Announcing the 2020 shortlist, the Director of the T.I.C., Roland Chavasse, said that technology-driven innovations will ensure the long-term future of the tantalum market will thrive and the Ekeberg Prize will encourage research and development. “Winners of the Anders Gustaf Ekeberg Tantalum Prize will be acknowledged as true leaders in this field”, he added.
The award is administered by the Tantalum-Niobium International Study Center (T.I.C.), the global trade body representing the tantalum and niobium industry.
The seven publications on the short list show the great versatility of tantalum:
- Fabrication of porous tantalum and tungsten black coatings for artificial earth satellites
- Tantalum (Ta) and niobium (Nb) containing alloy powders for application in additive manufacturing
- Tantalum recycling by solvent extraction: chloride is better than fluoride
- Discovery of ω-free high-temperature Ti-Ta-X shape memory alloys from first-principles calculations
- Tantalum bone implants printed by selective electron beam manufacturing (SEBM) and their clinical applications
- Tantalum(V) 1,3-propanediolate beta-diketonate solution as a precursor to sol–gel derived, metal oxide thin films
-
Remelt processing and microstructure of selective laser melted Ti25Ta
The winner will be chosen by the independent panel of experts and the Prize medal, made from pure tantalum metal, will be awarded at the T.I.C.’s 61st General Assembly (annual conference). The T.I.C.’s conference is the largest annual gathering of tantalum and niobium industry leaders, with delegates from every sector of the global industry.
The 2019 winner was Nicolas Soro and his colleagues for their paper "Evaluation of the mechanical compatibility of additively manufactured porous Ti–25Ta alloy for load-bearing implant applications". Information about this paper, and photos from the award ceremony, are available in Bulletin #180.
