Preparation method of hydroxyapatite-based composite fluorescent ceramic
The invention discloses a preparation method of hydroxyapatite-based composite fluorescent ceramic and relates to the technical field of ceramic preparation.The preparation method comprises the steps that firstly, a three-neck flask is taken, a diammonium hydrogen phosphate solution is added into the three-neck flask, the three-neck flask is put into an ice bath and stirred after ammonia water is added, the PH value of the solution is detected in the stirring process, stirring is stopped when the PH value of the solution reaches about 11, and first mixed liquid is prepared; europium nitrate is taken and dissolved in a calcium nitrate solution, the solution is added into the first mixed solution through a funnel after dissolution, stirring is conducted in the adding process, ammonia water is dropwise added, the pH of the solution is kept to be about 11, and a third mixed solution is prepared after dropwise adding is completed; transferring the mixed solution III into a hydrothermal kettle for heating, cooling, pouring out supernatant liquid, washing precipitates with absolute ethyl alcohol for multiple times, putting into a drying oven for drying after washing, and putting into a grinding machine for grinding after drying, so as to prepare hydroxyapatite-based composite powder; and filling a graphite mold with the hydroxyapatite-based composite powder, and then putting the graphite mold into an SPS sintering furnace for high-temperature sintering to obtain the fluorescent ceramic after sintering.
本发明公开了一种羟基磷灰石基复合荧光陶瓷的制备方法,涉及陶瓷制备技术领域,本发明首先取三口烧瓶并添加磷酸氢二铵溶液,添加氨水后放入冰浴中并搅拌,搅拌过程中检测溶液的PH值,当溶液PH达到11左右时,停止搅拌,制得混合液一;取硝酸铕并溶于硝酸钙溶液,溶解后通过漏斗加入混合液一中,加入过程中进行搅拌并滴加氨水使溶液保持pH在11左右,滴加完毕后制得混合液三;将混合液三转移到水热釜中进行加热,冷却后倒去上层清液,用无水乙醇多次洗涤沉淀物,洗涤后放入烘箱内进行干燥,干燥后放入研磨机中进行研磨,制得羟基磷灰石基复合粉体;将羟基磷灰石基复合粉体填入石墨模具中,然后放到SPS烧结炉中进行高温烧结,烧结后制得荧光陶瓷。
