Abstract In this work three different preparation techniques of biphasic calcium phosphate bioceramics (consisting of both hydroxyapatite and β-tricalcium phosphate) are compared: sintering of synthetic calcium-deficient apatites, sintering of mechanical mixture of synthetic hydroxyapatite and apatitic tricalcium phosphate and sintering of mechanical mixture of synthetic HAp and calcium metaphosphate glass. Two different HAp/TCP phase ratios were investigated. Phase composition, microstructure, sintering properties and microporosity of obtained bioceramics were investigated. The open porosity of prepared BCP bioceramics is strongly influenced by phase composition and preparation technique. BCP bioceramics SBCP and MBCP have homogeneous microstructure, whereas GBCP has inhomogeneous inclusions of dense TCP. High content of hydroxyapatite (HAp) phase in MBCP and SBCP correlates with high microporosity.
