YTTRIUM Usage And Synthesis
DescriptionThe element was discovered in 1794 by the Swedish chemist Gadolin. He named it after the small town Ytterby in Sweden where the mineral containing yttria was found. Mosander in 1843 determined that the yttria consisted of three oxides: yttria, erbia, and terbia. Yttrium occurs in all rare earths. It is recovered commercially from monazite sand, which contains about 3% yttrium. It also is found in bastnasite in smaller amounts of about 0.2%. Abundance of yttrium in earth’s crust is estimated to be 33 mg/kg. The metal has been detected in moon rocks.
Yttrium alloys have many applications. The metal doped with rare earths such as europium is used as phosphor for color television receivers. When added to iron, chromium, vanadium, niobium, and other metals it enhances resistance of these metals and their alloys to high temperature oxidation and recrystallization. It is a deoxidizer for vanadium and other nonferrous metals. Yttrium-aluminum garnets are used in lasers and in jewelery gemstones. Yttrium-iron garnets are used as transmitters and as transducers of acoustic energy.
PreparationYttrium is recovered commercially from its two principal sources, xenotime and monazite. Ore is opened by digestion with hot sulfuric acid. Insoluble residues are filtered out and leachate solution containing yttrium and other rare-earths is loaded onto cation exchange resin beds for separation. Fractions are eluted with ethylenediamine tetraacetic acid (EDTA) buffered with ammonia at varying temperatures. Also, many other chelates are highly effective in eluting rare earths. Such temperature adjustments of resin beds enhance separation efficiency, particularly for separating yttrium. Separated rate earths including yttrium are converted into insoluble oxalates that precipitate when treated with oxalic acid or sodium oxalate.
Yttrium oxalate is then ignited to its oxide, Y2O3. The oxide is heated at 750°C in a stream of anhydrous hydrogen fluoride to yield yttrium fluoride, YF3. Alternatively, the oxide is mixed with ammonium hydrogen fluoride NH4HF2 and heated at 400°C in a stream of dry air or helium. Yttrium metal may be produced from its fluoride either by metallothermic reduction or electrolysis. The more common metallothermic reduction involves reducing the fluoride with redistilled calcium in 10% excess over the stoichiometric amounts at elevated temperatures:
2YF3 + 3Ca → 2Y + 3CaF2
In the electrolytic process, a fused bath of yttrium fluoride and lithium fluoride is heated to nearly 1,700°C and electrolyzed. The electrolysis is done in a graphite crucible using molybdenum cathodes at which yttrium is produced as molten metal.
Yttrium is purified by distillation at high temperatures under vacuum.
Chemical Propertiessolid
General DescriptionSoft silvery-white metal in bulk. Dark-gray to black odorless powder. Mp: 1509°C; bp 2927°C. Density: 4.47 g cm-3 at 20°C. May irritate the respiratory tract if inhaled as a powder. May irritate the digestive tract if swallowed. Vapors may cause dizziness or suffocation.
Reactivity ProfileYTTRIUM in bulk is stable in air due to the formation of oxide films. Powder or dust is light-sensitive and air-sensitive and flammable in the air and (Hazardous Chemicals Desk Reference, p. 861(1987)). Reacts with water to form gaseous hydrogen (H2). Reacts with strong oxidizing agents, strong acids, strong bases, and halogens. The products of these reactions are irritating and toxic.
