Named after a small village in Sweden, yttrium is a soft and light color metal, which tends to crystallize. This element naturally occurs in minerals as yttrium phosphate. Yttrium has no biological importance and is slightly toxic. It is mainly used in metallurgy and also for producing radars. It has many applications in alloys with other metals like magnesium or aluminum. Yttrium was used to produce filters for microwave ovens, and it was an important element for producing colors in old TV technology. This element can also be used for producing LED lights and lasers. It also plays a role as a radioactive element in medicine for treating some types of cancer.
