Nano-hydroxyapatite ceramic and preparation method thereof
The invention relates to a nano-hydroxyapatite ceramic and a preparation method thereof and belongs to the technical field of ceramic processing. The nano-hydroxyapatite ceramic is prepared from the following components in parts by weight: 20-50 parts of hydroxyapatite, 40-60 parts of Al2O3, 10-20 parts of CaO, 1-10 parts of ZrO2, 1-10 parts of Y2O3 and 1-10 parts of CaF2. The preparation method of the nano-hydroxyapatite ceramic comprises the following steps of: matching the components according to a proportion, adding an alcohol solution, mixing uniformly, kneading, evaporating a solvent in a water bath at the temperature of 80 DEG C, heating to expand in a drying oven at the temperature of 70-90 DEG C, molding, putting the molded blank into a muffle furnace, increasing the temperature of the muffle furnace to 1,000-1,200 DEG C slowly, treating the blank for 8-10 hours, cooling, and taking out of the muffle furnace to obtain a finished product of the nano-hydroxyapatite ceramic. The nano-hydroxyapatite ceramic provided by the invention is a three-dimensional nano-porous expanded product, has the porosity of 90% or higher and is suitable for scaffold materials and bone repair materials in the bone tissue engineering.
