Low temperature preparation of α-tricalcium phosphate and its mechanical properties
In this work, α-tricalcium phosphate (α-TCP) was successfully prepared by the thermal transformation of amorphous calcium phosphate (ACP) precursor. β-cyclodextrin (β-CD) was used for preparation of ACP precursor and played an important role in designing its special structure. The phase composition...
