“…In Figure 1 Calcination also plays a crucial role in removing organic compounds and impurities that may hinder the formation of hydroxyapatite (HAp) [15]. Consequently, after the calcination process, the eggshell is expected to be converted into CaO, reducing the sample's mass [16].…”

Eggshells containing CaCO3 have potential as bioceramics for several tissue engineering applications. The content of CaCO3 converted into Ca(OH)2 can be used as a precursor to implant material. The purpose of the study was to compare two methods of converting CaO into Ca(OH)2 as the primary material for making hydroxyapatite. The method used is direct contact with air and dissolution with water. Hydroxyapatite synthesis using Ca(OH)2 is calcined from CaCO3 with a sintering temperature of 900 °C. The result of calcination is in the form of CaO. The stages of obtaining Ca(OH)2 by converting CaO using two methods, namely direct contact with air and dissolution with water. The XRD characterization results obtained that Ca(OH)2 results from direct contact with air show the formation of phase (portlandite), which is characterized by its presence at the highest typical 2θ angles = 18.18°, 28.68°, 34.30°, 47.40°, 50.92°, 54.16°, and 62.62°. The XRD Ca(OH)2 pattern with the distilled water distribution process shows the formation of a phase (portlandite) characterized by its presence at angles of 2θ = 18.18°, 28.68°, 34.30°, 47.40°, 50.92°, 54.16°, and 62.62 °. The results of FTIR Ca(OH)2 characterization of air contact and water dissolution showed strong O-H functional groups at wave numbers 3643 cm-1 and 3642 cm-1, C-O groups at 1487 cm-1 and 1483 cm-1. This suggests that both methods can convert CaO to Ca(OH)2, which synthesizes hydroxyapatite. The hydroxyapatite characterization results obtained have met the standard.

“…Hydroxyapatites, chemically represented as Ca10(PO4)6(OH)2, play a vital role in the composition of mammalian hard tissues [37] and exist in natural phosphate mineral deposits [38]. Hydroxyapatites can be sourced from natural materials such as mammalian bones, shells, fish scales, and minerals [39][40][41][42][43][44][45][46]. Their crystal structure possesses two distinct planes [47,48].…”

Carbonate hydroxyapatite is the common derivative of hydroxyapatite found in living systems. It is the building block of most hard tissues, including the teeth and bones. A vast majority of the applications of this versatile material focus on its biomedical applications, which is attributable to its closeness to biological apatites. Hydroxyapatite is a strong precursor to carbonate apatite in nature, and many experiments show that both are similar in a few respects. A significant divergence point is carbonate's obvious impact on its physicochemical properties and concomitant applications. The inclusion of carbonate ions into the lattice of hydroxyapatite results in morphological and physicochemical changes that vary with the method of synthesis and extent of substitution. The unique crystal structure, improved surface area, and porous morphology of carbonate hydroxyapatites also make it useful for catalysis and environmental remediation as adsorbents for heavy metals. This review briefly examines carbonate hydroxyapatite, its synthesis, its modification, and its characterization. It also highlights its biomedical applications while drawing attention to its non-medical potential.

“…A variety of methods have been used to get HAp, such as precipitation (Rizkayanti and Yusuf, 2019), microwave irradiation (Castro, et al 2022), reflux method (Cahyanto, et al 2017), heat treatment (Lolo, et.al. 2022), interfacial reaction with multiple emulsion, Solid-state syntesis (Khalid and Chaudhry, 2020) cationic surfactant template (Yusuf, et al 2019), sol-gel (Charlena, et al 2022), etc, Heat treatment known as the simplest and cheapest method because there is no need to mix additional sources to obtain HAp (Sunil & Jagannatham, 2016).…”

Hydroxyapatite (HAp) biomaterials have been successfully obtained from Channa striata and Scomberomorus commerso fish bone. Heat treatment was chosen as the method to get it. Heat treatment was done at 400oC, 600oC, and 800oC. The X-ray diffractometer (XRD) was used to determine the crystalline phase and crystallography properties. Based on XRD data and JCPDS 09-0432, all samples showed the phase of HAp. However, the β-TCP phase has been found in samples from Scomberomorus commerso, which calcined at 600oC and 800oC. The crystallite size of HAp from Channa striata fish bone increased as followed by higher temperature, and Scomberomorus commerso has the same crystallite size on samples that calcined at 600oC and 800oC. The microstrain of both samples has the same trend: the higher the temperature, the lower the microstrain. The temperature also affected the crystallinity sample; the higher the calcined temperature, the improved crystallinity. Fourier Transform Infrared (FTIR) data determined the functional groups of samples. The functional groups that appeared were OH-, PO43-, and CO32-. The mass of samples before calcined differs from after calcined, where the mass after calcined is smaller than before. The higher the temperature we used, the more decreased yield percentage we got.
