Holmium Oxide Formula Ho2O3
CAS No. 12055-62-8
Molecular Weight 377.86
Appearance Light yellow
Solubility Insoluble in water, moderately soluble in strong mineral acids
Stability Slightly hygroscopic
Application: Holmium Oxide is also called Holmia, has specialized uses in ceramics, glass, phosphors and metal halide lamp, and dopant to garnet laser. Holmium can absorb fission-bred neutrons, it is also used in nuclear reactors to keep atomic chain reaction from running out of control.

Individual Rare earth including Lanthanum, Cerium, Neodymium, Praseodymium, Samarium, Europium, Gadolinium, Dysprosium, Terbium, Holmium, Erbium, Ytterbium, Lutetium, Thulium, Scandium and Yttrium.


With the advanced extraction lines, we separate Rare Earth mixed compounds to 99% to 99.9999% various purities of individual and co-precipitated Rare Earth chemicals, including Oxides, Acetates, Chloride, Carbonates, Hydroxides, Fluorides, Nitrates, Oxalates, totally covered 90% of Rare Earth products, applied widely in manufacturing tri-band phosphors, advanced ceramics, pigments, glass, glazes, laser crystals, Rare Earth doped fibers.

With higher requirements for quickly developing technology, the advanced materials can provide with higher surface area, smaller or large particle size for specialty applications.

By additional Ion-Exchange facility, we process individual Rare Earth oxides to a purity of 99.9999% high-tech Rare Earth doped performance materials.

Details available upon request. Thank you!

CUSTOMERS SATISFACTION is our definite aim and is applied to our whole business activities.
