摘要

摘要本研究的主要目的是研究双相磷酸钙(biphasic calcium phosphate, BCP)的力学性能。双相磷酸钙是一种从海洋资源如印度对虾(Fenneropenaeus Indicus)壳类生物废弃物中提取的生物材料。我们报道了从虾壳生物废料中提取的羟基磷灰石和八磷酸钙的混合物BCP，在80°C和pH值为10的条件下采用湿法化学合成。BCP的XRD结果表明，在不同温度下烧结时，β-TCP和α-TCP等次生相与HA共存。此外，SEM和EDS打开了烧结良好的单轴晶粒和微量元素如Fe, Mg, Si和Na的存在。1100℃烧结试样的抗压强度最高，达到56.8 MPa，这是由于晶界处的MgO对晶界扩散起了重要作用。因此，虾壳生物废弃物衍生的BCP具有良好的力学性能，是高强度骨替代品的理想材料。

Preparation and structural characteristics of biphasic calcium phosphates from prawn shell bio-waste

ABSTRACT The major objective of the work is to explore the mechanical properties of biphasic calcium phosphates (BCP), a biomaterial derived from marine resources like prawn (Fenneropenaeus Indicus) shell biowaste through wet chemical treatment of CaO. We report the BCP, a mixture of hydroxyapatite and octa calcium phosphate from prawn shell biowaste using wet chemical synthesis at 80°C under pH 10. XRD of BCP revealed the coexistence of secondary phases like β-TCP and α-TCP along with HA upon sintering at different temperatures. Furthermore, the SEM and EDS opened well-sintered uniaxial grains and the presence of trace elements like Fe, Mg, Si, and Na. The specimens sintered at 1100°C showed the highest compression strength of 56.8 MPa due to MgO at the grain boundaries, which plays an important role in grain boundary diffusion. Therefore, the prawn shell biowaste-derived BCP has good mechanical properties, making them suitable materials for high-strength bone substitutes.
