# Polishing & Superabrasive Powders Source: https://powdchem.com/products/ceramic-powders/polishing-superabrasives/ Page type: Material category Advanced ceramic powders Polishing and superabrasive powder inquiries. Match the abrasive identity, particle profile and workpiece before choosing a grade. [Browse 6 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Diamond abrasives Separate monocrystalline, polycrystalline and nanodiamond requirements. Begin with the workpiece and target finish, then particle distribution and oversized-particle limits. #### Monocrystalline diamond powder monocrystalline diamond (MCD) superabrasive powder [Selection guide]() [Ask about this material]() C #### Polycrystalline diamond powder polycrystalline diamond (PCD) superabrasive powder [Selection guide]() [Ask about this material]() C #### Nanodiamond powder nanodiamond powder [Selection guide]() [Ask about this material]() C ### Oxide polishing powders Choose ceria, alumina or silica against the workpiece and polishing process. Compare agglomeration, dispersion state and the conditions used to assess removal and finish. #### Cerium oxide polishing powder cerium oxide (ceria; CeO2) polishing powder [Selection guide]() [Ask about this material]() CeO2 #### Alumina polishing powder alumina (Al2O3) polishing powder [Selection guide]() [Ask about this material]() Al2O3 #### Silica polishing powder silica (SiO2) polishing powder [Selection guide]() [Ask about this material]() SiO2 ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Abrasive system** Distinguish monocrystalline/polycrystalline diamond, nanodiamond, CBN and oxide polishing powders. Keep the chemistry and structure explicit. **Particle & surface** Specify the size range and distribution method, morphology, agglomeration and surface treatment needed by your tool or slurry. **Workpiece & finish** Describe the substrate, removal/finish target and process. A nominal particle size does not determine scratch performance by itself. ## Before you choose **Is cubic boron nitride the same product as hexagonal BN?** No. c-BN/CBN is a different crystal structure and an abrasive material identity. The BN formula must be accompanied by the phase and intended abrasive grade. **What does this directory cover?** Finished abrasives, grinding tools and prepared polishing compounds need separate supply briefs; they are not presented as dry powder here. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Abrasive identity and crystal/particle type - Particle distribution and oversized-particle limits - Surface treatment and dispersion medium - Workpiece, process and finish objective ### 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. [How we coordinate documents]() [Samples and testing]() [Send a material request]() ## Applications to explore.
