Define the composition family and the thermal or biological research task. [Browse 6 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Glass, silica and microsphere powders Borosilicate glass, quartz and hollow glass microspheres have different structures and process roles. Include the composition and particle form in the request. #### Borosilicate glass powder borosilicate glass powder (SiO2-B2O3 glass family; exact composition is grade-specific) [Selection guide]() [Ask about this material]() SiO2-B2O3 glass system #### Quartz powder Quartz powder (SiO2) [Selection guide]() [Ask about this material]() SiO2 #### Hollow glass microspheres hollow glass microspheres (glass microballoons; composition is grade-specific) [Selection guide]() [Ask about this material]() Multi-component glass ### Calcium-phosphate and bioactive-glass research Keep hydroxyapatite (HA), tricalcium phosphate (TCP) and 45S5 glass separate. Phase and composition evidence support material comparison; regulated-use qualification needs its own brief. #### Hydroxyapatite powder hydroxyapatite (HAp; Ca10(PO4)6(OH)2) bioceramic powder [Selection guide]() [Ask about this material]() Ca10(PO4)6(OH)2 #### Tricalcium phosphate powder tricalcium phosphate (TCP; Ca3(PO4)2) bioceramic powder [Selection guide]() [Ask about this material]() Ca3(PO4)2 #### 45S5 bioactive glass powder 45S5 bioactive glass powder (nominal SiO2-CaO-Na2O-P2O5 system) [Selection guide]() [Ask about this material]() SiO2-CaO-Na2O-P2O5 / 45S5 ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Composition & phase** Separate glass, partially crystalline glass-ceramic and crystalline phosphate powders. Multi-component glasses do not have one universal chemical formula. **Thermal & particle profile** State the particle distribution, softening/firing requirements and relevant expansion or thermal data and methods. **Application scope** Describe sealing, co-firing, coating, composite or research use. A biomedical research material listing does not imply device approval or clinical suitability. ## Before you choose **Can a glass name replace its composition and thermal brief?** It cannot establish compatibility with a substrate or firing route. Identify the glass family, relevant composition and processing window before comparing options. **What does this directory cover?** Glass beads, microspheres, frits and loose powders are identified by their actual form. Finished glass and medical devices are not powder-supply claims. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Glass/composition family or phosphate formula - Particle distribution and physical form - Thermal requirements and test methods - Intended application and evaluation documents ### 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.
