Development of triphasic calcium phosphate–carbon nanotubes (HA/TCP-CNT) composite: a preliminary study

Triphasic calcium phosphate, composed of a more stable phase hydroxyapatite (HA) and highly soluble tricalcium phosphates (α- and β-TCP) has been synthesized through hydrothermal method. In the present work, an in-situ method to disperse 1wt% multiwall carbon nanotubes (MWCNTs) within HA/TCP powder...

In the present work, an in-situ method to disperse 1wt% multiwall carbon nanotubes (MWCNTs) within HA/TCP powder has been used in order to develop HA/TCP-CNTs composite.

HA/TCP-CNTs composite was found to have a significant of Vickers Hardness of 1.98 GPa after 1100oC sintering.
