Abstract
本发明涉及一种牙科用氧化锆基底饰面瓷及其制备方法。本发明将氧化锆(ZrO2)细粉加入稳定剂Y2O323%、CaO7%,氧化锆(ZrO2)总量约70%,以该复合细粉、交联剂和分散剂为原料,通过注凝成型制备生坯,在T=1700℃条件下(保温2‑4h)热压烧结制备本发明陶瓷。强度为800~1000MPa,韧性达20~25MPa·m↑。本发明提出氧化锆与饰面瓷难以匹配的关键在于二者膨胀系数的不匹配以及氧化锆相变过程中的体积突变,并通过对氧化锆陶瓷基底成分的调整解决二者匹配问题,同时降低玻璃陶瓷软化点,使其在氧化锆陶瓷相变区间处于软化状态,对陶瓷的体积变化不敏感突破以氧化锆陶瓷作为基底组分取代氧化铝的技术瓶颈,复合成新的牙科全瓷材料。
Description
技术领域
本发明属生物医药领域,具体涉及一种牙科用氧化锆基底饰面瓷及其制备方法。
背景技术
目前,氧化锆因具有高韧性、高强度等优点被认为是更为理想的口腔全瓷材料。但其与饰面瓷的结合问题成为它在此领域应用的瓶颈问题。国内大部分研究是通过对饰面瓷的调整,来满足与氧化锆陶瓷的匹配问题,但所研制饰面瓷的颜色难以达到临床应用的要求。
发明内容
针对现有技术的不足,本发明一种牙科用氧化锆基底饰面瓷及其制备方法。通过对氧化锆基底成分的调整和改变烧结技术来达到与玻璃饰面瓷相匹配,从而形成新的牙科全瓷材料。
一种牙科用氧化锆基底饰面瓷,该基底饰面瓷为以氧化锆为基底、Y2O3、CaO为稳定剂复合基底基底饰面瓷。
各组分比例按照摩尔比为为氧化锆70%、Y2O323%、CaO7%。
一种牙科用氧化锆基底饰面瓷的制备方法,按照以下步骤进行:
(1)将氧化锆(ZrO2)细粉加入稳定剂CaO7,ZrO2制备成复合细粉,组分比例按照摩尔比为氧化锆70%、Y2O323%、CaO7%;
(2)以该复合细粉、交联剂和分散剂为原料,通过注凝成型制备生坯,在T=1700℃条件下(保温2-4h)热压烧结制备,制备出来的陶瓷的强度为800~1000MPa,韧性达20~25MPa·m。
本发明提出氧化锆与饰面瓷难以匹配的关键在于二者膨胀系数的不匹配以及氧化锆相变过程中的体积突变,并通过对氧化锆陶瓷基底成分的调整解决二者匹配问题,同时降低玻璃陶瓷软化点,使其在氧化锆陶瓷相变区间处于软化状态,对陶瓷的体积变化不敏感突破以氧化锆陶瓷作为基底组分取代氧化铝的技术瓶颈,复合成新的牙科全瓷材料。
本发明具有以下有益效果及优点:
1.提出了氧化锆与饰面瓷难以匹配的关键在于二者膨胀系数的不匹配以及氧化锆相变过程中的体积突变,
2.通过对氧化锆陶瓷基底成分的调整解决二者匹配问题,从而与技术成熟的饰面玻璃陶瓷相匹配,突破以氧化锆陶瓷作为基底组分取代氧化铝的技术瓶颈,复合成新的牙科全瓷材料
