Yttrium aluminum garnet thermal barrier coating ceramic granulation powder as well as preparation method and application thereof
The invention belongs to the technical field of ceramic powder, and provides yttrium aluminum garnet thermal barrier coating ceramic granulation powder as well as a preparation method and application thereof. The method comprises the following steps: mixing aluminum hydroxide, yttrium hydroxide, a dispersing agent and water, sequentially carrying out ball milling and high-energy ball milling to obtain raw material powder, and then roasting to obtain clinker powder; mixing the clinker powder, a dispersing agent and water, and performing high-energy ball milling to obtain clinker slurry; and finally, mixing the clinker slurry with a binder, and granulating to obtain the yttrium aluminum garnet thermal barrier coating ceramic granulation powder. According to the invention, the defects of high reaction temperature, large and non-uniform particle size of the prepared powder, poor powder activity and the like in the traditional solid-phase reaction method are overcome; meanwhile, the concept of a green and environment-friendly production process is implemented, polluting ions such as acid radicals and ammonia radicals are not introduced in the powder preparation process, ceramic powder with the particle size closer to that of powder prepared through a chemical precipitation method can be obtained, and the development requirement of a new material preparation process in the future is met.
本发明属于陶瓷粉体技术领域，提供了一种钇铝石榴石热障涂层陶瓷造粒粉及其制备方法和应用。该方法包含下列步骤：将氢氧化铝、氢氧化钇、分散剂和水混合，顺次进行球磨和高能球磨，得到生料粉体，然后进行焙烧得到熟料粉体；将熟料粉体、分散剂和水混合，进行高能球磨得到熟料浆液；最后将熟料浆液与粘结剂混合进行造粒，得到钇铝石榴石热障涂层陶瓷造粒粉。本发明克服了传统固相反应法存在的反应温度高、制备的粉体粒度大且不均匀、粉体活性差等缺点；同时本发明贯彻了绿色环保生产工艺的理念，在粉体制备过程中不引入酸根、氨根等污染性离子，同时能够获得更接近化学沉淀法制备的粉体粒径大小的陶瓷粉体，符合未来新材料制备工艺的发展要求。
