Flame spray pyrolysis (FSP) processing conditions (O2 dispersion gas flow rate, precursor flow rate and concentration) and calculated precursor concentration used for the synthesis of the calcium phosphate (CaP) nanoparticles, along with their specific surface area (SSA) measured by N2 adsorption and the corresponded primary particle diameter (dBET).
| Sample | O2 Dispersion Gas Flow Rate (L/min) | Precursor Flow Rate (mL/min) | Ca and P Concentration (M) | Precursor Concentration in Flame (mmolCa+P/LO2disp) | SSA (m2/g) | dBET (nm) |
|---|---|---|---|---|---|---|
| CaPL | 3 | 8 | 0.2 | 0.533 | 73 | 26 |
| CaPS | 8 | 3 | 0.1 | 0.0375 | 246 | 8 |
