The invention belongs to the technical field of bioengineering and material science, and particularly relates to a preparation method of hydroxyapatite porous ceramic capable of being used as an artificial bone. The preparation process can be realized according to the following steps: taking deionized water, a dispersing agent, a binder, hydroxyapatite ceramic powder and a pore-forming agent as initial raw materials, and carrying out ball-milling mixing to obtain stably dispersed slurry; drying the obtained slurry in a rotary evaporator, and sieving the slurry for later use; carrying out mechanical press molding on the sieved powder, demolding the material, and drying the material in a drying oven; and sintering the dried green body in an air atmosphere furnace to obtain the hydroxyapatiteporous ceramic. The prepared material is reliable in performance, and has the characteristics of simple process, easiness in large-scale production and the like.
本发明属于生物工程及材料科学技术领域，具体涉及一种可用做人工骨的羟基磷灰石多孔陶瓷的制备方法。其制备过程可按如下步骤实现：以去离子水、分散剂、粘结剂、羟基磷灰石陶瓷粉体、造孔剂为起始原料配料，并进行球磨混合，得到分散稳定的浆料；将所得浆料在旋转蒸发仪中进行干燥，过筛后待用；将过筛后的粉体进行机压成型，脱模后在烘箱中进行干燥；将干燥的坯体置于空气气氛炉中进行烧结，得到羟基磷灰石多孔陶瓷。本发明所制备材料性能可靠，且具有工艺简单、易于规模化生产等特点。
