Yttrium Metal

Yttrium metal is a kind of rare earth elements, which is black gray metal. It is hard and brittle, which is ductile. Y can react with hot water and form hydrogen. When heating above 400℃, it ignite. Yttrium compounds are mainly yttrium oxide, yttrium fluoride, yttrium chloride and yttrium carbonate. It forms a layer of oxide in air, so it is stable. It dissolve in dilute acid and KOH solution.Yttrium metal can process into foil, sheet, wire, rod, ingot, lump, powder and so on. Yttrium powder is REM 99.9% and particle size -100mesh and -200mesh normally.

Yttrium metal mainly apply to production of red phosphor ( YVO4:Eu, Y2O3:Eu, Y2O2S:Eu) of colour TV picture tube. It is also for some ray filter, superconductor, super alloy and special glass.

Yttrium ingot can apply as nodulizing agent in nodular cast iron, desoxidant for vanadium and other nonferrous metals. It can improve property and strength of some alloys and metals as chromium, molybdenum, titanium zirconium, aluminum magnesium.

Yttrium aluminum garnet doping neodymium powder is excellent laser material. Yttrium iron garnet is excellent laser material too. Both two are new magnetic material.
