Light Rare Earth Oxides Powder

LREE: Lanthanum (La) to Europium (Eu), atomic numbers 57–63.

Have lower atomic numbers, relatively higher crustal abundance, and are widely used in metallurgy, catalysts, and glass polishing. For example, cerium oxide (CeO₂) is a key component in automotive exhaust catalysts, while neodymium oxide (Nd₂O₃) is critical for permanent magnets.

Light rare earth oxide powders, characterized by lower atomic numbers, are widely used in industry.

Heavy Rare Earth Oxides Powder

HREE: Gadolinium (Gd) to Lutetium (Lu) (atomic numbers 64–71), plus Yttrium (Y, atomic number 39), Yttrium is grouped with HREE due to its chemical similarity to heavy rare earths.

Have higher atomic numbers, lower crustal abundance, and are harder to isolate, but they exhibit unique optical and magnetic properties. Dysprosium oxide (Dy₂O₃) enhances high-temperature magnets, erbium oxide (Er₂O₃) is vital for fiber-optic amplifiers, and yttrium oxide (Y₂O₃) is used in phosphors and ceramics.

Heavy rare earth oxide powders, characterized by their rarity and unique functions in high-tech industries, are highly valued.
