Abstract
In this Research are interesting used eggshells to create a product with added value, such as nanoscale hydroxyapatite (HA). HA must have the appropriate nanoscale characteristics, such as crystallinity, particle size, shape, surface area, porous nature, and so on, because they contain calcium carbonate and biologically required trace elements such as Mg, Si, and others for many biological applications. The same effect can be obtained by adjusting the reaction parameters, selecting the appropriate synthesis mode, and employing organic modifiers. Eggshell bio-waste was used as the calcium source in this study to create hydroxyapatite powder. We investigated its characteristics for application in manufacturing a functionally graded material (NiTi/HA) utilized in bone culture. The powder was tested using XRD, FTIR, SEM, and a particle analyses. Whereas XRD revealed the structure of the resulting powder, which is comparable to the conventional form of HAP powder, FTIR revealed the presence of the primary compound Hydroxyapatite in producing powder, such as (P?4 3-, C?22- and bending OH-). As a result of this research, we can conclude that the synthetic eggshell produced HA has good particle size, bioactivity, and porous nature.
