Ytterbium (Symbol Yb, atomic number 70) – Marignac discovered a new component in the earth then known as erbia in 1878 which he called ytterbia. In 1907, Urbain separated ytterbia into two components which he called neoytterbia and lutecia. The elements in these earths are now knows as ytterbium and lutetium, respectively.

Holmium (Symbol Ho, Atomic number 67). The special absorption bands of holmium were noticed in 1878 by the Swiss chemists Delafontaine and Soret, who announce the existence of an “Element X”. Cleve, of Sweden, later independently discovered the element while working on erbia earth. The element is therefore named after Cleve’s native city. Holmia, the yellow oxide, was prepared by Homberg in 1911. To find out more about this rare earth visit our website.

Manganese is a metallic chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. As a free element, manganese is a metal with important industrial metal alloy uses, particularly in stainless steels, in aluminium alloys, as an additive in unleaded gasoline to boost octane rating and reduce engine knocking, and in newer alkaline batteries.
Osmium twinning / Osmium is a hard, brittle, blue-gray or blue-black transition metal in the platinum family & is the densest naturally occurring element, with a density of 22.59 g/cm3 (slightly greater than that of iridium & twice that of lead).
