Shortlist announced for 2018 Ekeberg Prize

26 June 2018

The shortlist has been announced for the 2018 Anders Gustaf Ekeberg Tantalum Prize (‘Prize’) and once again the breadth of applications for the element tantalum (Ta) are very impressive. The Prize is awarded annually for outstanding contribution to the advancement of the knowledge and understanding of the element tantalum (Ta).
Announcing the 2018 shortlist, the Director of the T.I.C., Roland Chavasse, said that the long-term future of the tantalum market will depend on technology-driven innovations and the 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 six publications on the shortlist show the great versatility of tantalum. Two describe improved catalysts, while the others cover surgical implants, solid state memory devices, and a new refining process for tantalum ore. The sixth publication is the first comprehensive treatise on the science, manufacture and applications of tantalum capacitors. 
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 59th General Assembly in Kigali, Rwanda, in October 2018.
