CHEMISTRY GLOSSARY
yttrium → itrij
Yttrium was discovered by Carl Gustaf Mosander (Sweden) in 1843. Named after Ytterby, a village in Sweden. It is silvery, ductile, fairly reactive metal. Exposed surfaces form oxide film. Easily combustible, reacts with oxygen in water to release hydrogen. Yttrium is found in minerals such as monazite, xenotime and yttria. Combined with europium to make red phosphors for colour TV’s. Yttrium oxide and iron oxide combine to form a crystal garnet used in radar.
zirconium → cirkonij
Zirconium was discovered by Martin Heinrich Klaproth (Germany) in 1789. The origin of the name comes from the Arabic word zargun meaning gold colour. It is grey-white, lustrous, corrosion-resistant metal. Exposed surfaces form oxide protective film. Zirconium is found in many minerals such as zircon and baddeleyite. Used in alloys such as zircaloy this is used in nuclear applications since it does not readily absorb neutrons. Also baddeleyite is used in lab crucibles. Used in high-performance pumps and valves. Clear zircon (ZrSiO4) is a popular gemstone.
