History
Dubnium was produced by competing teams: JINR Dubna in 1968 (claiming “nielsbohrium”) and Lawrence Berkeley National Laboratory in 1970 (claiming “hahnium”). The protracted IUPAC naming dispute was resolved in 1997, naming it after Dubna, Russia, where the JINR laboratory is located. The compromise resolved Cold War-era tensions over transactinide element naming.
Uses Today
Dubnium has no practical applications. Research focuses on its chemical properties as the first group-5 transactinide element — verifying whether relativistic effects cause it to deviate from the behaviour of niobium and tantalum above it in the periodic table.
Why We Don't Buy It
Why QuickStop Metals doesn’t buy Dubnium:
Dubnium is a synthetic transactinide element with a half-life of approximately 28 hours for its most stable isotope (dubnium-268). Only about 100 atoms have been produced in total across all experiments. No commercial production or scrap trade is possible.
Value & Pricing
No commercial market. Cannot be produced in macroscopic quantities.
