Element of the month - Manganese (Mn)

2019-05-03

This year it's 150 years ago that Dmítriy Ivánovich Mendeléyev first published the Periodic Law that would later become the periodic table. Unesco has decided to celebrate this by calling 2019 "International Year of the Periodic Table of Chemical Elements" (IYPT).

The fourth element is manganese (Mn) which was first used (manganese dioxide) by Carl Wilhelm Scheele to produce Chlorine. But it was not isolated as manganese until 1774 when Uppsala University alumni Johan Gottlieb Gahn managed to isolate an impure sample of manganese metal by reducing the dioxide with carbon.

They've found that Spartan steel contained manganese which made it exceptionally hard and it was later (early 1900s) used in steelmaking. Manganese dioxide has been used to produce Chlorine and also as part of the glassmaking process, it was called "glassmakers soap" because it was used to remove colour from glass.

It was also used in the first batteries, up until the nickel-cadmium and lithium battery.
