“…Moreover, Ahsan and Ahmed produced Ca-HA from eggshell by a precipitation method. 81 They studied the use of uncalcined and calcined eggshells in HA synthesis. The micrographs representing the microstructural features of the HA-based uncalcined eggshell exhibited a combination of spherical, hexagonal, and cylindrical shapes having crystal sizes of ∼30–60 nm.…”

Hydroxyapatites (HAps) synthesized from waste animal bones have recently gained attention due to their outstanding properties. This is because there is a need to fabricate scaffolds with desirable mechanical strength, ability to withstand high temperatures, and insoluble in solvents such as water, acetone, ethanol, and isopropyl alcohol. This study is an extensive summary of many articles on the routes of synthesis/preparation of HAp, and the optimum processing parameter, and the biomedical application areas, such as: drug administration, dental implants, bone tissue engineering, orthopedic implant coatings, and tissue regeneration/wound healing. A broad catalog of the synthesis methods (and combination methods), temperature/time, shape/size, and the calcium‐to‐phosphorous (Ca/P) value of diverse waste animal bone sources were reported. The alkaline hydrolysis method is proposed to be suitable for synthesizing HAp from natural sources due to the technique's ability to produce intrinsic HAp. The method is also preferred to the calcination method owing to the phase transformation that takes place at high temperatures during calcinations. However, calcinations aid in removing impurities and germs during heating at high temperatures. When compared to calcination technique, alkaline hydrolysis method results in crystalline HAp; the higher degree of crystallinity is disadvantageous to HAp bioactivity. In addition, the standardization and removal of impurities and contaminants, thorough biocompatibility to ensure clinical safety of the HAp to the human body, and improvement of the mechanical strength and toughness to match specific requirements for the various biomedical applications are the important areas for future studies.

In this study, microporous silicon dioxide nanoparticles (SiO2–NPs) were used to improve the physical, chemical, and mechanical properties of bone China ceramics. Microporous SiO2–NPs were prepared economically from sodium metasilicate (SMS) as a precursor with cetyltrimethylammonium bromide (CTAB) as a surfactant at different concentrations. The prepared SiO2–NPs were characterized using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectroscopy to confirm the formation of microporous SiO2–NPs. The optimum concentrations of the precursor and surfactant used in the SiO2–NPs synthesis were set to be 1.5% and 2 g/200 ml, with a size range of 7–96 nm. SiO2–NPs prepared at the optimum concentrations were incorporated into bone China at different concentrations to evaluate their effect on flexural strength and elasticity. The bone China prepared using 1% SiO2–NPs (B1) had the highest flexural strength and Young's modulus values. Sample characteristics, including self-cleaning, differential scanning calorimetry, thermogravimetric analysis, bulk density (BD), apparent porosity (AP), and water absorption (WA), were investigated. The results revealed outstanding characteristic such as self-cleaning ability, remarkable increase in AP and WA, and a decrease in BD.
