Abstract Nanobioceramics with enhanced mechanical and degradable properties are demanding for bone tissue engineering purposes. We report the influence of partial replacement of ZnO by tricalcium phosphate (TCP) on the improved structure, degradation and mechanical properties of sol-gel grown MgO-ZnO-TCP nanobioceramics. Sample containing 40 mol% of TCP revealed homogenous distribution of fine agglomerates composed of ellipsoidal plates-like particles of average diameter ≈25.42 nm and length ≈80.93 nm. Immersion test is performed to determine the degradation characteristics of the as-prepared samples. Sample containing 40 mol% of TCP presented the lowest degradation rate and delayed loss of the compressive strength. It is established that the proposed MgO-ZnO-TCP nanobioceramic composition with good mechanical properties and corrosion resistance are prospective for biodegradable implants.

溶胶-凝胶生长的 MgO-ZnO-磷酸三钙纳米生物陶瓷：机械和降解属性的评估

摘要 具有增强机械性能和可降解性能的纳米生物陶瓷对骨组织工程的目的有要求。我们报告了磷酸三钙 (TCP) 部分替代 ZnO 对溶胶-凝胶生长的 MgO-ZnO-TCP 纳米生物陶瓷的结构、降解和机械性能的影响。含有 40 mol% TCP 的样品显示由平均直径 ≈25.42 nm 和长度 ≈80.93 nm 的椭球板状颗粒组成的精细附聚物的均匀分布。进行浸泡试验以确定所制备样品的降解特性。含有 40 mol% TCP 的样品表现出最低的降解率和抗压强度的延迟损失。
