Explore materials]() ## Browse by chemical form Choose the compound formula, then the powder or prepared-feedstock requirements. ### Rare-earth fluorides Select the exact fluoride formula and required supplied form. Dry powders, granules and optical-deposition pieces are different purchasing items; include particle size, moisture and the relevant impurity limits. #### Yttrium fluoride powder Powder versus granule, purity basis, oxygen/moisture and process. [Ask about this material]() YF3 #### Ytterbium fluoride powder Powder form, impurity basis and optical/formulation requirement. [Ask about this material]() YbF3 #### Lanthanum fluoride powder Dry powder form, moisture and relevant optical/chemical limits. [Ask about this material]() LaF3 #### Neodymium fluoride powder Powder form, composition and material-specific documents. [Ask about this material]() NdF3 #### Gadolinium fluoride powder Powder form, purity basis and intended process. [Ask about this material]() GdF3 ### Yttrium oxyfluoride For YOF, include the phase and oxygen/fluorine ratio. If the request is for spray feedstock, also specify the particle architecture and equipment requirements. #### Yttrium oxyfluoride powder Phase, O/F ratio, morphology and spray-feedstock architecture. [Ask about this material]() YOF; phase and O/F ratio need confirmation ### Hydroxide precursors Keep La(OH)3 and Nd(OH)3 distinct from their oxides. Compare moisture and particle profile, with any calcination step described in the process brief. #### Lanthanum hydroxide powder Hydroxide identity, carbonate/moisture, particle profile and calcination need. [Ask about this material]() La(OH)3 #### Neodymium hydroxide powder Hydroxide identity, moisture, particle profile and precursor use. [Ask about this material]() Nd(OH)3 ### Cerium-zirconium mixed oxide Specify the Ce/Zr ratio and target phase. For catalyst-support evaluation, include the surface-area or pore data and the conditions used to measure them. #### Cerium zirconium mixed oxide powder Ce/Zr ratio, phase, BET/porosity and catalyst-support evaluation. [Ask about this material]() Ce-Zr-O / Ce1-xZrxO2-based; ratio varies ### Related chemical forms [Browse rare-earth oxides](), or use the related-material categories below for elemental metals and magnetic alloys. ## Questions before sampling **Should I request an oxide, a fluoride or a hydroxide?** Use the chemical form required by your formulation or process. An element name such as yttrium is incomplete: Y2O3, YF3 and YOF are different materials. If you have a reference datasheet, send it with the inquiry. **Can raw powder be supplied as spray feedstock?** Describe the particle structure and size window required by the spray equipment. A raw chemical powder and a prepared spray feedstock need separate specifications; we will check the requested form. **Where are the rare-earth oxide powders?** The rare-earth oxide category contains the 16 oxide catalogue entries. This page covers the other compound directions listed above; use the related-material link below for oxides. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Exact compound, composition and crystal phase - Dry powder, granule or prepared feedstock requirement - Particle profile, moisture and impurity basis - Application, quantity, destination and documentation ### Quantity, samples and documents Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums. We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements.
