I'm extracting hydroxyapatite(HAp) from fish bone and using it as a precursor for my Urea-HAp nanohybrid for my undergrad research. My first method is calcination of Fishbone ;
CaCaO3 ----(heat 900 degrees)---------> CaO + CO2
CaO + H2O ------------> Ca(OH2)
After making the suspension, I will use it to synthesize Urea-HA nanohybrids using a one-step in situ approach where H3PO4 (0.6 M, 250.0 cm3 ) will be added dropwise to a suspension containing Ca(OH)2 (19.3 g, 250.0 cm3 ) and urea (150.0 g). Subsequently, these mixtures will be flash-dried to obtain dry nanohybrids. Here, the presence of urea in the medium allows for its coating on HA NP as the nucleation occurs. The method is adapted from (Amaratunga et.al, 2017), but they did not use Fishbone as a precursor for the Ca(OH2).
Please give your comments and suggestions about my approach and whether or how should I make the Ca(OH)2 suspension?
Good day! I suppose you should have 250cm3 overall. As far, Ca(OH)2 density is 2.211 g/cm3, thus, you need 42.6723 g of Ca(OH)2, suspended in 230.7 cm3 of water.
