Antioxidant composite ceramic aerogel and preparation method thereof
The invention discloses antioxidant composite ceramic aerogel and a preparation method thereof, and belongs to the technical field of composite ceramic aerogel. The main body of the antioxidant composite ceramic aerogel is silicon nitride aerogel, and the nanostructure of the silicon nitride aerogel is one or a combination of two of a one-dimensional silicon nitride nanowire and a two-dimensional silicon nitride nanobelt. The nano structure of the silicon nitride aerogel is sequentially coated with a mullite coating and a copper-nickel metal coating from inside to outside. The technical problem that the silicon nitride ceramic aerogel stably serving in the high-temperature aerobic environment cannot be prepared in batches at low cost in the prior art can be solved.
本发明公开了一种抗氧化复合陶瓷气凝胶及其制备方法，属于复合陶瓷气凝胶技术领域。所述抗氧化复合陶瓷气凝胶的主体为氮化硅气凝胶，所述氮化硅气凝胶的纳米结构为一维氮化硅纳米线和二维氮化硅纳米带中的一种纳米结构或两种纳米结构的组合；所述氮化硅气凝胶的纳米结构上由内向外依次包覆有莫来石涂层和铜镍金属涂层。本发明能够解决现有技术无法低成本且批量化制备高温有氧环境中稳定服役的氮化硅陶瓷气凝胶的技术问题。
