Rare Earth Metals
Rare earth metals are important functional materials for advanced materials research, magnetic materials, photonics, energy technologies, and high-end manufacturing. This material family generally includes scandium, yttrium, and the lanthanide elements, valued for their distinctive magnetic, optical, electronic, and alloying properties.
This category supports research, materials development, and professional procurement requirements across different rare-earth elements, purity grades, physical forms, and custom specifications. Materials may be selected as lumps, granules, powder, pieces, evaporation materials, sputtering targets, or alloy feedstock according to the intended process.
Material performance depends on elemental composition, purity, physical form, and impurity control. For vacuum deposition, magnetic materials, optical applications, or precision alloy development, confirm the required element, purity, size, packaging, and equipment compatibility before procurement.

Handling and Storage
Some rare earth metals are chemically active, especially fine powders, small particles, and freshly exposed metal surfaces. Depending on the material, protection from air, moisture, or elevated temperatures may be appropriate. Follow the product label, SDS, and technical documentation for storage, transport, and handling guidance.
For high-purity metals, evaporation materials, magnetic materials, and custom alloys, use suitable tools, containers, and handling procedures to help reduce contamination and maintain material consistency.
Frequently Asked Questions
Which elements are included in rare earth metals?
Rare earth metals generally include scandium, yttrium, and the lanthanide elements, such as lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, ytterbium, and lutetium.
What is the difference between light and heavy rare earth metals?
Light rare earth metals commonly include lanthanum through europium and are widely used in magnetic materials, catalysis, hydrogen storage, and glass or ceramics. Heavy rare earth metals commonly include gadolinium through lutetium, together with yttrium, and are important for high-performance magnets, photonics, laser materials, and specialty functional materials.
Should I choose lumps, granules, pieces, or powder?
Lumps, granules, and pieces are commonly used for melting, batching, and source loading. Powder is generally more suitable for powder metallurgy, blending, reaction synthesis, and formulation development. Select the form that matches your equipment, process, and required material quantity.
Can rare earth metals be used for vacuum deposition?
Yes. Depending on the deposition method, rare earth metals may be used as evaporation pellets, pieces, lumps, or sputtering targets. Confirm whether your process uses thermal evaporation, electron-beam evaporation, or magnetron sputtering, as well as the required loading dimensions.
How should I select a purity grade?
Select purity based on the sensitivity of your application. Standard research may use a practical purity level for the experiment, while thin films, optical materials, electronic materials, and high-performance magnetic materials may require closer control of purity and key impurities.
Can rare earth metals be supplied in custom specifications?
Custom requirements may include the selected element, purity, material form, size, particle range, package quantity, and alloy composition. This is useful for specialized source loading, materials development, and process-specific applications.
Do rare earth metals require special storage?
Storage requirements vary by element and material form. Some rare earth metals, particularly powders and fine particles, may require sealed, dry, or inert-gas-protected storage. Always follow the product label, SDS, and technical documentation.
