Overview of β-TCP characteristics: (a): ESEM Image HFW 46.6 μm (fracture surface); HV: 10 kV; LFD detector @ 100 Pa; (b): µCT of porosity of the β-TCP taken by Scanco Micro-CT 50 at 90 kV, 4 W, 44 µA at a resolution of 2 μm and an integration time of 5000 ms ; (c): Pore size distribution; measurements of the Pascal-140 porosimeter (1000 μm–1.4 μm; pressure increase to 0.1 kPa) in blue and the Pascal-440 porosimeter (1.4 μm–1.8 nm; pressure increase to 400 MPa) in purple (Porotec Pascal 140/440, Hofheim, Germany); (d): XRD pattern of the TCP (Bruker D8 Advance, Billerica, USA; Bragg-Brentano geometry; Cu anode; secondary graphite monochromator; scintillation counter; 40 kV/40 mA; 1°2-theta/ min; step size 0.02°2theta) and Rietveld Refinement with Profex 4.3
