Product Name:Cerium
English Name:Cerium
CAS No.:13550-45-3
Aliases:Cerium metal, Metallic cerium, Cerium ingot
Molecular Formula:Ce
Physical Properties:Cerium is a silver-gray active metal, soft and ductile, readily oxidized in air, and tends to form a dark oxide film on the surface. Powdered cerium may ignite spontaneously in air. Density 6.77 g/cm³, melting point 798°C, boiling point 3426°C, insoluble in water, soluble in dilute acids.
Uses:Mainly used as an additive in steel and non-ferrous metals, and as a hydrogen storage matrix material; also can be used as a reducing agent for preparing other rare earth metals.
Technical Specifications:
Purity: 99%, 99.5%, 99.9%
Appearance: silver-gray metal ingot, mechanically polished, can be cut according to customer requirements
Total rare earth content ≥99%; relative cerium purity ≥99% (Ce-2N) or ≥99.5% (Ce-2N5)
Impurity limits: rare earth impurities ≤1% or ≤0.5%; Fe≤0.2%, Mg≤0.02%, Mo≤0.03%, Si≤0.04%, Al≤0.04%, C≤0.03%
Packaging: inner double-layer plastic bag, vacuum argon filling optional, outer iron drum, 50 or 100 kg per drum
