α-Tricalcium Phosphate (α-TCP) is a core reactive phase widely used in calcium phosphate cement (CPC) systems and resorbable bone repair formulations. Its hydration/conversion behavior makes it especially suitable for injectable and moldable cement platforms where setting time, handling, and strength must be engineered.

Why α-TCP is a strong fit for CPC

Controllable working and setting window: By tuning particle size distribution (PSD) and surface area (BET), the reaction rate and handling time can be adjusted for different clinical and manufacturing needs.

  • Flexible phase design: α-TCP can be formulated with TTCP, DCPA/DCPD, HA and other phases to achieve targeted setting chemistry and final phase composition.
  • Engineering-friendly powder properties: Flowability, packing, and consistency can be tailored to improve mixing behavior and batch stability.

Typical use cases

  • Injectable CPC systems for orthopedic bone defect filling.
  • Resorbable bone repair formulations requiring controlled conversion behavior.
  • Composite systems where α-TCP acts as the reactive backbone.

We provide implant-grade α-TCP powders and multi-dimensional customization across PSD, BET, phase control, and morphology, with practical technical support for OEM and R&D programs. Share your target working time, setting time, and mechanical requirements, and we can recommend a realistic parameter range and sampling approach.
