More About Yttrium
What the name means: Yttrium is named after a village called Ytterby, near Stockholm, Sweden. It was from a quarry near Ytterby village that a black mineral, which was named ytterite (gadolinite), that contained yttrium salts, was found.
Who identified yttrium?: The black mineral Ytterite was investigated by a Finnish chemistry professor called Johan Gadolin in 1794. It proved to be made up of a mixture of many compounds. Gadolin found that about 38% of Ytterite (also known as gadolinite) was made the oxide of a new "earth". He called this oxide yttria. In 1828, Friedrich Wohler isolated yttria and extracted an impure sample of the element Yttrium. In fact, Yttrium is not a rare earth metal but belongs to the group of metals known as transition metals.
