چکیده | ||
Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natural source as raw materials using microwave irradiation without any further heat treatment. To compare the proposed approach various combination of micro irradiation and heat treatment as traditional and more recent developments were performed. Characterizations of products were carried out using XRD, SEM and TEM techniques. The results confirmed the presence of minor constituents (Mg, Sr, C, O) and the ratio of Ca/Mg=1.63 in the products. Moreover, the formation of relatively spherical shape like nanoparticles of hydroxyapatite (about 30 nm) was confirmed by TEM images during the direct preparation of HA nanoparticles by employment of microwave irradiation. According to the results, the proposed approach provide the possibility of the preparation of large-scale, spherical and pure HA nanoparticles in acceptable time by usage of low cost natural source, eco-friendly method without the using of organic solvent and expensive raw materials. | ||
