Rare Earth Material

 

TYR supplying all kinds of rare earth product as Rare Earth Metal, Rare Earth Oxide, Rare Earth Alloy, Rare Earth Mischmetal, Rare Earth Boride, Rare Earth Fluoride, Rare Earth Chloride, Rare Earth Nitride e.t.c

 

TYR supplying those Rare Earth material base on Sputtering Targets, evaporation materials and shapes as like powder, pieces, granules, pellets, rods, wires, foils, disks, discs, plates are available.

 

Generally, rare earth element include light rare earth element, LREE and heavy rare earth elements, HREE, the LREE include Lanthanum, La, Cerium, Ce, Praseodymium, Pr, Neodymium, Nd, Samarium, Sm, Europium, Eu, the HREE include Gadolinium, Gd, Terbium, Tb, Dysprosium, Dy, Holmium, Ho, Erbium, Er, Thulium, Tm, Ytterbium, Yb, Lutetium, Lu.

 

The Rare earth element are use in a wide application, such as rare earth doped fiber, metallurgy industry, ceramic industry, electron and television industry, atomic energy industry, chemical industry, chemurgy, glass industry e.t.c.

 

What’s means is for the purity of especial Rare Earth Material, here is the answer:

In rare earth industry, chemical purities of rare earth oxides and compounds are often presented on rare earth oxide basis (REO basis), i.e., content of a specific rare earth oxide in comparison to total rare earth oxides (TREO) present: REO/TREO. The statement of "CeO2 > 99%", often means CeO2/TREO > 99%. To obtain its absolute purity of a specific oxide, you can use formula: REO/TREO X Percentage of TREO in the material.

 

Purity on Rare Earth Metal Basis.

 In rare earth industry, chemical purities of rare earth metals are often presented on rare earth metal basis (REM basis)), i.e., content of a specific rare earth metal in comparison to total rare earth metals (TREM) present: REM/TREM. The statement of "Ce > 99%" often means Ce/TREM > 99%. To obtain its absolute purity of a specific metal, you can use formula: REM/TREM X Percentage of TREM in the material.

 

B. Price Calculation of Rare Earth Compounds.

 

In rare earth industry, a formula is used to calculate the actual prices of rare earth compounds, such as carbonate, hydroxide and chloride: Actual price of rare earth compound = Price of 100% of TREO (Total rare earth oxide) X Percentage of TREO in the compound. For instance,
