Description
技术领域
本发明涉及陶瓷生产领域,具体涉及透明陶瓷及其制备方法。
背景技术
目前,建筑市场中所采用的墙地建筑装饰材料大多为天然石材、釉面砖、玻化砖等,但天然石材由于其具有对人体有害的放射性,耐化学腐蚀性差及抗折强度低等不足限制了其使用范围;釉面砖材料表面质感好,但存在着易龟裂、不耐磨及抗冻性差等不足,玻化砖的理化性能最为突出,但一直以来因陶瓷材料本身的原因均没有透光的质感,装饰效果不如釉面砖及 微晶玻璃复合板的效果好,人们希望有一种具有良好的装饰效果,又具有优良特性的建筑材料。
多数的透明陶瓷应用在光学领域,较少用于建材领域。
发明内容
本发明解决的技术问题为透明陶瓷生产难度大的问题,提供透明陶瓷及其制备方法。
为了解决上述技术问题,本发明提供的技术方案为:
透明陶瓷的制备方法,包括:
S10.取纳米氧化铝粉90~100质量份,纳米碳粉3~5质量份,微米碳粉1~2质量份,氧化钇0.05~0.1质量份,氧化镧0.01~0.05质量份,氧化镁0.1~0.5质量份;
S20.将纳米氧化铝粉体同纳米碳粉、微米碳粉混合后球磨1h,烘干,过筛后,在氮气气氛中1650~1750℃煅烧2h得到中间粉体;
S30.将中间粉体同氧化钇、氧化镧、氧化镁混合,球磨1h,烘干,过筛,将得到的粉体压制成砖,在200MPa下冷等静压成型,在1800~2000℃下烧结4h,冷却后,得到透明陶瓷。
利用碳热还原法制备ALON中间粉体,再将中间粉体同烧结助剂共同烧结,从而得到透明陶瓷。
对透明陶瓷的制备方法进行调整,以扩大透明陶瓷的体积。
优选地,纳米氧化铝粉96~100质量份,纳米碳粉4~5质量份,微米碳粉1.5~2质量份,氧化钇0.06~0.1质量份,氧化镧0.04~0.05质量份,氧化镁0.4~0.5质量份。
优选地,纳米氧化铝粉96质量份,纳米碳粉4质量份,微米碳粉1.5质量份,氧化钇0.06质量份,氧化镧0.04质量份,氧化镁0.4质量份。
优选地,所述纳米氧化铝的粒径为10~30nm,所述纳米碳粉的粒径为10~30nm,所述微米碳粉的粒径为1~10μm。纳米碳粉可以提高反应活性,降低反应温度;微米碳粉有助于合成纯度较高的AlON粉体,进而提高透明陶瓷的透光性,对粒径进行优化,并同时使用两种粒径的碳粉,优化不同粒径的碳粉的用量,从而提高透明陶瓷的性能,降低透明陶瓷的生产难度。
优选地,所述S20步骤中:

透明陶瓷,根据上述方法制成的透明陶瓷。
发明人在多年的研究实践中发现,透明陶瓷的透光率和其硬度难以同时提高。透明陶瓷的厚度很难做的较厚,厚度提高后透光率难以提高,这样就难以通过提高材料的体积来改变材料的力学性能。
碳热反应是制备透明陶瓷所需粉末的一种手段,纳米碳粉利于提高反应活性,降低反应所需温度,微米碳粉有助于提高陶瓷的透光性。现有技术很少将两者混合起来制备粉末,发明人将两者结合起来,以探索降低反应难度并提高陶瓷的透光性。发明人发现,在5mm的陶瓷厚度下,较难实现较高的透光率,如果过分提高粉末的性能,例如增加大量的微米碳粉,则反应难度过大。
偶然情况下,发明人发现增加纳米碳粉的比例,在陶瓷厚度较大的情况下,透明度有了一定的提升,虽无法达到1mm厚度的陶瓷的透光率,却也有了显著的提高。因此,发明人对纳米碳粉和微米碳粉的比例,纳米碳粉的性质进行了进一步优化,从而提高了5mm厚的透明陶瓷的透光率和硬度。
与现有技术相比,本发明具有的有益效果为:对透明陶瓷的制备方法进行调整,以扩大透明陶瓷的体积;同时没有显著降低陶瓷的透光性,并且提高了陶瓷的硬度,同时提升了陶瓷的厚度、硬度、透光性。

实验例
采用紫外-可见分光光度计(UV-2550型,Shimadzu公司)测量样品在波长700nm处的透过率(样品厚度抛光至5mm);采用维氏硬度计(FV-700型,Future-Tech公司)测量样品硬度,测试压力选为9.8N,加载时间为15s。
表1 各实施方式的透明陶瓷的性能
各实施例或对比例用于测试的样品的厚度为5mm,厚度较大,透光率不及2mm厚度的样品,但是实施例1和4在5mm的厚度下也达到了70%的透光率,为进一步提高透明陶瓷的厚度提供了可能。
实施例1和4的透光率较高,与碳热还原过程中选用的碳粉组合有关,纳米碳粉和微米碳粉混合可以提高透光率,同时降低反应难度,在1650~1750℃得到中间粉体。实施例1、4同对比例相比,透过率有较为显著的提高,这是由于,对比例3中的微米碳粉和纳米碳粉的比例不同,反应难度较高,导致不能有效的得到中间粉体。
实施例1和4的强度高于其他实施方式,发明人为了提高透明陶瓷的透光率并降低生产难度的过程中,尝试了多种途径,对碳粉的组成进行优化,并对碳粉进行部分改性,可以改善透明陶瓷的透光效果,并意外的发现陶瓷的硬度也有提升,这为增加陶瓷厚度创造了条件。
上列详细说明是针对本发明可行实施例的具体说明,以上实施例并非用以限制本发明的专利范围,凡未脱离本发明所为的等效实施或变更,均应包含于本案的专利范围中。
