Lanthanum Metal Foils.
Lanthanum La 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. Holmium Powder Purity: Ho/REM 99.9% 3N CAS No.:7440-60-0 EINECS No.:231-169-0 Molecular Formula:Ho Molecular Weight:164.930 Melting Point:1474℃ Boiling Point:2695℃ Density:8.79 Applications Holmium metal powder can apply in material of highfield. It is raw material for producing magnetic alloys material.
