The invention relates to the technical field of transparent ceramics, and particularly discloses a preparation method of magnesia-alumina transparent ceramics, which comprises the following steps: adding alumina and magnesia-alumina into a dispersion regulator in an amount which is 5-10 times of the total amount of alumina according to a weight ratio of (8-12): 1, then adding modified hydroxyapatite in an amount which is 2-5% of the total amount of alumina, and stirring and mixing. According to the magnesia-alumina transparent ceramic disclosed by the invention, alumina and magnesia-alumina are used as matrixes for matching, a graphene agent formed by matching graphene with a hydrochloric acid solution, pentadecyl phenol and a dopamine agent is adopted, a chitosan compounded lanthanum oxide solution is used as a rare earth active agent through lanthanum oxide, and chitosan and a sulfuric acid solution are used for assisting, so that the permeability of the product is improved; and meanwhile, the interfacial property among the raw materials of the product is optimized, so that the strength and light transmission performance of the product are enhanced in a coordinated manner.
本发明涉及透明陶瓷技术领域，具体公开了一种氧化镁铝透明陶瓷的制备方法，包括以下步骤：将氧化铝、氧化镁铝按照重量比(8‑12):1加入到氧化铝总量5‑10倍的分散调节剂中，然后加入氧化铝总量2‑5％的改性羟基磷灰石，搅拌混合。本发明氧化镁铝透明陶瓷通过氧化铝、氧化镁铝作为基体配合，采用石墨烯与盐酸溶液、十五烷基酚和多巴胺剂配合的石墨烯剂，而壳聚糖复配氧化镧溶液通过氧化镧作为稀土活性剂，通过壳聚糖与硫酸溶液协助，改进产品的通透性，同时优化产品原料之间的界面性，进而协调式增强产品的强度和透光性能效果。
