Properties Suppliers
Europium Metal Purified 99.9%

Europium metal is steel grey metal of body-centered cubic lattice, which is soft and ductile. It is rare earth element, which is available with powder, foil, rod, piece, ingot, granule, slug, sputtering target. Eu react rapidly with oxygen and water. When heating to 150~180℃, it fires in air. Europium powder tend to ignite, which is most active among rare earth metals. There are two production method, reduction and distillation. Distilled Eu piece is dendritic with higher purity than reduced Eu metal.

Lithium Sulfide LAB GRADE 99%

Lithium Sulfide

 

Lithium Sulfide is white to yellow crystals, which have smell of sulfur. It is typical sulfide of lithium. It is stable at home temperature and pressure, however react with water sharply. Li2S tend to absorb moisture in air and oxidize. When heating to 200℃, Li2S react with iodine and form lithium iodide. It react with carbon in electric-arc furnace and form lithium carbide. Lithium metal and pure sulfur are the raw materials.
