Yttrium powder is made from yttrium metal, including yttrium metal by reduction method and distillation method. Nano yttrium powder should be gotten by homogeneous redution method. Although yttrium ingot is silver, it is gray when processed into fine particles. The partice size is avalable with -100mesh and -200mesh. It oxidizes in air and forms a lay of oxide, so it is relatively stable. When heat to 400℃, it would fire. Yttrium metal react with water to release hydrogen. It is soluble in dilute acid and KOH solution and form various salts. Yttrium could alloy aluminum, zirconium, silver, molybdenum, iron, manganese, palladium, platinum and so on. It should avoid acid, oxide, alkali metal and air for storage.

Yttrium powder 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.
