Holmium Metal Purified 99.9%

Holmium powder is dark gray fine particles, which has  unusual magnetic property. It is stable at room temperature and in dry air, however in dry air and high temperature, it is easy to oxidize. It is soluble in inorganic acid. Holmium metal can compound with various nonmetal elements nearly. It exists in gadolinite, monazite and other rare earth ores. Holmium chloride is the raw material. Ho can process into foil, sheet, rod, powder, wire and sputtering target. The ingot is of REM 99.99% by distillation method. Ho powder is of REM 99.9% and particle size -100mesh and -200mesh. There are two production method of holmium ingots, distillation method and reduction method. The distilled holmium piece is dendritic with higher purity than reduced one.

Yttrium Oxide Purified 99.9%

Yttrium oxide is white to light yellow powder, which is a kind of rare earth oxides. It is insoluble in dilute acid, however nearly insoluble in water.

Yttrium Oxide

CAS No.:1314-36-9 EINECS No.:215-233-5 Molecular Formula:Y2O3 Molecular Weight:225.81
Melting Point:2439℃ Boiling Point:4300℃ Density:5.03 Flash Point:12℃

Applications

Yttrium(III) oxide granule can apply to thermal spray. For this application, it process into spherical large particle to get great flow ability. It should guarantee the whiteness too. Normally the production method is granulation.

Yttrium trioxide is important material for magnetic material for microwave and military project, which is also for optical glass. It can improve the refractive index of special glass and reduce dispersion index. So it is raw material for high brightness fluorescent powder for large-screen television and coating of other kinescope.

Yttria apply to produce thin film capacitor , special refractory material, high pressure mercury lamp, laser, memory parts and other magnetic bubble material. It is also for artificial laser crystal and superconductive material.

Yttrium(III) oxide powder is additive for lanthanum series glass and high temperature resistance and rediation resistance optical glass. It is also important additive for silicon nitride engineering ceramics, zirconium dioxide engineering ceramics, piezoelectric ceramics, photoelectric ceramics, semiconductor ceramics, thermistor ceramics, capacitor ceramics and other functional ceramics.

Yttria powder mainly apply to prepare new magnetic material yttrium iron garnet and solid laser material yttrium aluminum garnet (YAG). It is also a kind of hydrogen storage material.
