45S5 bioactive glass is well known for its bioactivity in bone regeneration and related biomedical applications. In microsphere form, it becomes even more manufacturing-friendly - offering better flow, packing, and integration into composite systems such as calcium phosphate, polymers, and injectable platforms.

Why microspheres matter

  • Better flow and handling: Microspheres often improve dosing, mixing, and processing consistency versus irregular powders.
  • A functional additive in composites: 45S5 microspheres are frequently used as a bioactivity booster in CaP-based or polymer-based systems.
  • Process-oriented customization: Particle size range and surface characteristics can be tailored to your processing window and performance targets.

Typical application directions

  • CaP composites (HA / β-TCP / α-TCP) for enhanced bioactivity.
  • Injectable bone repair materials and cement modification.
  • Porous scaffolds and composite scaffolds.
  • Dental bone grafting and regenerative material systems.

If you are developing a composite formulation, define your target size range, mixing ratio, and process route (injectable, molding, printing, sintering, etc.). We can align microsphere parameters to your manufacturing constraints and validation plan.
