Preparation method of magnesium oxide/hydroxyapatite porous composite material
The invention discloses a preparation method of a magnesium oxide/hydroxyapatite porous composite material, and belongs to the technical field of biomedical materials. The method comprises the following steps: by taking nano magnesium oxide powder and nano hydroxyapatite powder as raw materials, proportioning the magnesium oxide powder and hydroxyapatite according to the mass percent of (1-10%): (99-90%), weighing, ball-milling, drying and grinding to obtain composite powder; mixing the composite powder with medical-grade ammonium bicarbonate according to a volume percentage ratio of (40-80%):(60-20%), uniformly mixing, and pressing to obtain a long-strip-shaped green body; and preparing the magnesium oxide/hydroxyapatite porous composite material by spark plasma sintering. The porosity of the prepared composite material is 20%-60%, the pore size is 100-500 [mu] m and is controllable, and the composite material meeting various different requirements, such as bone scaffolds, bone filling and repair materials of hard tissue defect parts, can be prepared according to actual requirements.
本发明公开一种氧化镁/羟基磷灰石多孔复合材料的制备方法，属于生物医用材料技术领域。本发明所述方法以纳米氧化镁粉末和纳米羟基磷灰石粉末为原料，其中氧化镁粉末与羟基磷灰石按质量百分比1％～10％:99％～90％进行配比，称取，球磨，烘干，研磨后得到复合粉末；将复合粉末与医用级碳酸氢铵按体积百分比40％～80％:60％～20％进行混合，混合均匀压制得到长条状坯体；采用放电等离子烧结制备出氧化镁/羟基磷灰石多孔复合材料。本发明所制备出的复合材料孔隙率在20％～60％，孔径尺寸在100～500μm且可控，可根据实际的需求，制备出满足各种不同需求的复合材料，如骨支架、骨填充及硬组织缺损部分的修复材料等。
