Nanostructure lutetium disilicate feed as well as preparation method and application thereof
The invention relates to a nanostructure lutetium disilicate feed as well as a preparation method and application thereof. The method comprises the following steps: (1) carrying out ball milling on nano Lu2O3 powder and nano SiO2 powder to obtain mixed slurry; the molar ratio of the nano Lu2O3 powder to the nano SiO2 powder is 1: (2.4 to 2.6); (2) performing spray granulation on the mixed slurry to obtain composite powder; (3) carrying out high-temperature sintering on the composite powder to obtain a nanostructure lutetium disilicate feed; and the nanostructured lutetium disilicate feed does not contain lutetium monosilicate Lu2SiO5. The prepared nanostructure lutetium disilicate feed is high in purity, the product does not contain Lu2SiO5, the internal structure of the nanostructure lutetium disilicate feed is nanocrystals, the nanostructure lutetium disilicate feed is uniform in particle size distribution, high in compactness, good in fluidity and large in tap density, the performance of a subsequent coating can be greatly improved, and the nanostructure lutetium disilicate feed is suitable for a plasma spraying process.
本发明涉及一种纳米结构双硅酸镥喂料及其制备方法和应用。所述方法包括如下步骤：(1)将纳米Lu2O3粉体和纳米SiO2粉体进行球磨，得到混合浆料；所述纳米Lu2O3粉体和纳米SiO2粉体的摩尔比为1：(2.4～2.6)；(2)将所述混合浆料进行喷雾造粒，得到复合粉体；(3)将所述复合粉体进行高温烧结，得到纳米结构双硅酸镥喂料；所述纳米结构双硅酸镥喂料不含有单硅酸镥Lu2SiO5。本发明制备的纳米结构双硅酸镥喂料纯度高，产物中不含Lu2SiO5，纳米结构双硅酸镥喂料内部组织为纳米晶，喂料粒度分布均匀、致密性高、流动性好、振实密度大，可以大大提高后续涂层的性能，适合用于等离子喷涂工艺。
