“…The banana peel pectin mediated green facile synthesis route is a low-cost approach capable of producing n-HAP. The crystallinity and crystallite size of n-HAP decreased with increase of pectin concentration as it was evidenced from XRD [84]. Also, the SEM results (Fig.…”

Bioceramics are the materials which can enhance the quality and longevity of human life. Hydroxyapatite (HAP) is a readily considered bioceramic material for artificial bone substitution in biomedical field due to its compositional resemblance to the bone mineral and very good biocompatiblity. Recently, HAP has attracted significant interest in drug delivery and bone tissue engineering applications. The human cortical bone consists of biological HAP which is found within collagen as nanodimensional crystalline aggregates. There has been enormous effort in developing bioactive synthetic ceramics that could closely mimic the fine and complex structure of human bone. Though HAP is highly biocompatible and bioactive, it possesses poor mechanical properties. In order to overcome this drawback, attempts are made toward the synthesis of mineralized HAP. Several methodologies have been investigated and developed for the synthesis of pure and substituted HAP. Modern research deals with novel HAP nanostructure formulations with properties closer to those of living bone, aiming at improved and more effective biomedical applications. This chapter presents the facile and cost-effective synthesis methods of pure and substituted HAP nanoparticles such as sol-gel approach, hydrothermal techniques, etc., toward effective biomedical applications.

“…Further, the green template method proves to be the best method rather than the chemical and physical methods, as it is economical, environment friendly, easily scaled up for large scale synthesis and in this method there is no need to use high pressure, energy, temperature and toxic chemicals. Very recently Gopi et al, successfully synthesized HAP particles using sucrose, tartaric acid and pectin derived from the natural sources, as green templates [36][37][38].…”

Hydroxyapatite (HA) was synthesized from chicken bone waste by calcination. Pectin was extracted from orange peels by microwave irradiation, and 1 and 3 wt % of pectin was incorporated into the HA. The resulting powders were then pressed into disk samples before being sintered at temperatures of 1050, 1150, and 1250 °C for 2 h. Various analytical techniques, including Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, density measurement, and Vickers microhardness tests, were used to evaluate the characteristics and mechanical properties of the samples. The incorporation of pectin did not interfere with the pure phases of HA, and minimal amounts of β‐tricalcium phosphate were detected in the XRD patterns. Both ball milling and the addition of pectin effectively reduced the particle size of HA. However, the addition of pectin above 1 wt % did not contribute significantly to the densification and hardness of chicken bone‐derived HA (CHA) compared with ball‐milled CHA. Samples sintered at 1050 °C had the lowest relative density, owing to incomplete particle fusion. Increasing the sintering temperature resulted in a maximum relative density of ca. 95 % and a Vickers microhardness of 4.12 GPa for ball‐milled CHA samples sintered at 1250 °C. Sintering temperature and ball milling were observed to play a more significant role in the densification and hardness of CHA compared with the addition of pectin.
