Preparation method of tetragonal phase BaTiO3/HA hollow microspheres with micro-nano pore structure
The invention discloses a preparation method of a tetragonal phase BaTiO3/HA hollow microsphere with a micro-nano pore structure, and belongs to the technical field of biological ceramic materials. The method comprises the following steps: mixing BaTiO3 and HA in an atomic scale in a liquid phase state, fixing the BaTiO3 and the HA in a liquid precursor form, carrying out liquid nitrogen wet freezing forming on the precursor powder subjected to rotary evaporation, carrying out freeze drying, and carrying out high-temperature calcination to successfully prepare the tetragonal phase BaTiO3/HA microspheres with a specific micro-nano pore channel structure. In the synthesis process, common inorganic salts and simple reagents are mainly used, the cost is low, the method is simple and feasible, the repeatability is very good, and the synthesized tetragonal-phase BaTiO3/HA microspheres with the micro-nano pore channel structure are high in performance, good in stability, suitable for large-scale production and capable of promoting the commercialization process of biological ceramic materials.
本发明公开了微纳孔道结构四方相BaTiO3/HA空心微球的制备方法，属于生物陶瓷材料技术领域。该方法首先在液相状态下将BaTiO3和HA完成原子尺度的混合并以液态前驱体形式固定下来，再将旋蒸后的前躯体粉末进行液氮湿法冷冻成型，冷冻干燥后通过高温煅烧过程成功制备出具有特定微纳孔道结构的四方相BaTiO3/HA微球。本发明合成过程中主要以常见的无机盐和简单的试剂为主，成本低，简单易行且重复性很好，合成的微纳孔道结构四方相BaTiO3/HA微球性能高，稳定性好，适合大规模生产，能够推进生物陶瓷材料商业化进程。
