Production of poorly crystalline tricalcium phosphate nanopowders using different mechanochemical reactions

Poorly crystalline nano-sized tricalcium phosphate powders were successfully synthesized by two distinct mechanochemical reactions. Results revealed that the structural features as well as morphological characteristics were influenced by the chemical composition of reagents. The obtained nanopowders exhibited average sizes about 21 and 28 nm. According to the TEM/SEM observations, the synthesized powders showed cluster-like structures composed of spheroidal particles with a mean size of about 23 nm and ellipsoidal particles with an average size of about 30 nm. The proposed method as a new vision in powder technology can be used for mass production of nanostructured tricalcium phosphates.
