a silvery metallic element that is common in rare-earth minerals; used in magnesium and aluminum alloys
A silvery metallic element. It is found in almost every lanthanoid mineral, particularly monazite. Yttrium is used in various alloys, in yttrium-aluminum garnets used in the electronics industry and as gemstones, as a catalyst, and in superconductors. A mixture of yttrium and europium oxides is widely used as the red phosphor on television screens. Symbol: Y; m.p. 1522°C; b.p. 3338°C; r.d. 4.469 (20°C); p.n. 39; r.a.m. 88.90585. [DC99
A rare elemental metal. A radioactive form of yttrium is used in radiation therapy and some types of immunotherapy.
Enhances cell growth, and extends their life. Has been shown to double the life span of laboratory animals. It is an ionic plant source mineral.
Yttrium (IPA: ), is a chemical element in the periodic table that has the symbol Y and atomic number 39. A silvery metallic transition metal, yttrium is common in rare-earth minerals and two of its compounds are used to make the red color phosphors in cathode ray tube displays, such as those used for televisions.
