Phase-Pure Hydroxyapatite/β-Tricalcium Phosphate Scaffolds from Ultra-Pure Precursors: Composition Governs Porosity, Strength, and SBF Kinetics

Abstract

depletion increased with β-TCP content, consistent with more extensive surface apatite formation in β-TCP-rich scaffolds. Collectively, these data are consistent with a composition-dependent sequence-β-TCP content → densification/porosity → strength → degradation/apatite kinetics-within the tested conditions and inform parameter-based tuning of BCP scaffolds for non-load-bearing indications (e.g., alveolar ridge preservation, craniofacial void filling).
