Erbium Oxide Purified 99.9%

Erbium oxide is pink powder, which is rare earth oxide. It is insoluble in water, but soluble in acid. Er2O3 absorb CO2 and H2O in air to form subcarbonate salts. It is stable at room temperature and pressure. When heating to 1300℃, it turns into hexagonal crystal and not melt. Its property and production method is close to other lanthanum series elements.

Erbium Oxide

CAS No.:12061-16-4 EINECS No.:235-045-7 Molecular Formula:Er2O3 Molecular Weight:382.52
Density:8.64 Melting Point:1522℃ Boiling Point:2355℃  


Erbium(III) oxide mainly applies as dopant of yttrium iron garnet and control material of nuclear reactor. It is also raw material for special luminescent glasses and infrared absorbing glass.

Erbium trioxide is colorant for glass, which make glass show rosy. It is also additive for yttrium aluminum garnet laser material and activating agent for fluorescent powder. It is catalyst for prepare oil chemicals.

In producing crystal glass, it need remove yellow color that caused by 3+ iron ion. Adding erbium(III) oxide with or without neodymium oxide remove yellow efficiently.

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.
