技术领域
本发明涉及一种彩色渐变氧化锆材料及其制备方法,属于牙科用陶瓷材料技术领域。
背景技术
氧化锆陶瓷由于具有较高的抗弯强度和断裂韧性,成为了一种重要的结构陶瓷,又由于发现氧化锆陶瓷具有很好的生物相融性,还具有优良的稳定性,如耐磨损和耐腐蚀等,能够解决全陶瓷牙科修复体中存在的强度低、韧性差的问题,因此被广泛应用于牙科领域,但是氧化锆陶瓷多呈现白色,颜色单一,无法满足自然牙的色彩分布规律。另外,目前氧化锆陶瓷的种类较多,其透性不一,如普透、高透及超透等,且用同一种染色液对其进行内染时的呈色效果也不一样,造成了工序的繁琐和复杂。因此,有必要对氧化锆陶瓷的制备方法进行研究。

纳米氧化锆粉体70-99
氧化铁0.5-20
氧化铒0.5-20。
其中,氧化锆材料的相对密度为0.992-0.998。
本发明所述的彩色渐变氧化锆材料的制备方法,包括以下步骤:
(1)配料:
将纳米氧化锆粉体、氧化铁、氧化铒分别按不同配比混合成三份;
(2)装模成型:
将步骤(1)中按不同比例混合的粉料分别依次置于膜腔的不同位置,经干压成型后,得到坯体;
(3)烧结;
将步骤(2)中得到的坯体进行真空包装后放入冷等静压机中进行等静压成型,然后将其置于马弗炉中进行预烧结,采用CAD/CAM***进行切削后再进行二次烧结,得到彩色渐变氧化锆材料。
其中,优选的技术方案如下:
步骤(1)中纳米氧化锆粉体占70-99wt%,氧化铁占0.5-30wt%,氧化铒占0.5-30wt%。
步骤(2)中干压成型压力为60-100MPa。
步骤(3)中等静压成型压力为200-300MPa。
步骤(3)中预烧结温度为900-1050℃,二次烧结温度为1450-1550℃。
本发明的有益效果如下:
本发明制得的氧化锆材料的相对密度为0.992-0.998,其制备过程无需内染,只需要由医生确定颜色后选用相应颜色的锆块,经CAD/CAM雕铣机切削后直接放于烧结炉中进行烧结,既满足了自然牙的颜色分布规律又简化了工艺过程,其应用市场广泛。
