作为本发明进一步的方案：改性黄长石粉末采用黄长石在350-460摄氏度下焙烧30-60分钟，焙烧后的产物放入乙醇中浸泡10-25分钟，然后烘干并且研磨成粉末得到。
作为本发明进一步的方案：骨粉采用鱼骨粉、牛骨粉、羊骨粉和猪骨粉的一种或者多种的混合物，蓖麻油采用大豆油、菜籽油和橄榄油中的一种或者多种的混合物。
所述医用陶瓷材料的制备方法，具体步骤如下：
步骤一，将氧化铝粉末、氧化锆粉末、磷酸铝、纳米氧化锌和珍珠粉投入球磨机中研磨30-90分钟，得到第一混合物；
步骤二，将改性黄长石粉末、氧化硅、蓖麻油和白云石粉末分散在无水乙醇中形成混合浆料，然后进行干燥即可得到烧结助剂；
步骤三，将第一混合物、氧化镁粉末和骨粉混合得到第二混合溶液，然后对第二混合溶液缓慢滴加氨水并且进行缓慢搅拌，直至第二混合溶液的PH值为7.8-8.9，然后将第二混合溶液放入反应釜中并且在1580-1750摄氏度下保温15-40分钟，得到第三混合物；
步骤四，将第三混合物和烧结助剂放入热压模具中进行烧结压制，然后降温冷却即可得到成品。
与现有技术相比，本发明的有益效果是：本发明原料来源广泛，制备工艺简单，适用于工业的大规模生产；本发明制备的陶瓷材料不仅硬度大和生物相容性好，而且耐酸碱性能和抗菌效果好，适用于制备义齿或者骨骼，市场前景广阔。
