Bioactive coatings (R&D): why 45S5 composition is the starting point

For 45S5 programs, the most important “spec line” is not purity—it’s composition. Once the composition is defined, particle size, morphology, and processing determine deposition behavior and reactivity.

Recommended products

• 45S5 Bioactive Glass (micro) for general R&D and blending
• 45S5 Microspheres for flow and packing‑controlled programs
• 45S5 (Nano) for surface activity studies (define dispersion protocol)
