Discovery & History
Moscovium was first synthesised in 2003 at JINR Dubna by Yuri Oganessian, Vladimir Utyonkov, and colleagues in collaboration with Oak Ridge National Laboratory, by bombarding americium-243 with calcium-48 ions. Named in 2016 after Moscow Oblast — the administrative region surrounding Moscow where JINR is situated. About 100 atoms have been produced in total.
Where It's Used
Moscovium has no practical applications. It is studied purely to understand the properties of superheavy elements and the “island of stability” — a predicted region of the periodic table where certain superheavy nuclides may have significantly longer half-lives than their neighbours.
Can You Sell It?
Why QuickStop Metals doesn’t buy Moscovium:
Moscovium’s most stable isotope has a half-life of approximately 220 milliseconds — less than a quarter of a second. It exists only briefly as individual atoms in particle accelerators. No commercial application or scrap trade is possible.
Price Guide
No commercial market. Produced only at JINR Dubna using intense calcium-48 beams at a cost of millions of pounds per experimental run.
