TaC ceramic precursor, TaC ceramic and preparation method
The invention belongs to the technical field of carbide ceramic preparation, and discloses a TaC ceramic precursor, TaC ceramic and a preparation method. The preparation method of the TaC ceramic precursor comprises the following steps: S1, adding citric acid monohydrate and tantalum pentachloride powder into absolute ethyl alcohol at the water bath temperature of 10-20 DEG C to obtain a first solution; s2, heating the first solution obtained in S1 in a water bath to 30-50 DEG C, adding deionized water, continuously stirring, and keeping the temperature for 20-40 minutes to obtain a second solution; s3, dropwise adding ethylene glycol into the second solution obtained in S2, uniformly stirring, and standing for 20-30 minutes to obtain a third solution; and S4, heating the third solution obtained in S3 to 50-70 DEG C in a water bath, and keeping the temperature for 0.5-2 hours to obtain a precursor solution. The precursor prepared by the method is a stable organic compound containing carbon and tantalum elements, can be stored for a long time, and is simple in preparation process and low in production cost, and the finally obtained TaC ceramic is high in purity.
本发明属于碳化物陶瓷制备技术领域，公开了一种TaC陶瓷先驱体、TaC陶瓷及制备方法。制备TaC陶瓷先驱体包括以下步骤：S1、将一水合柠檬酸和五氯化钽粉体加入至无水乙醇中，水浴温度为10～20℃，得到第一溶液；S2、将S1得到的所述第一溶液水浴加热至30～50℃，加入去离子水并不断搅拌，保温20～40min，得到第二溶液；S3、向S2得到的所述第二溶液中滴加乙二醇，搅拌均匀后静置20～30min，得到第三溶液；S4、将S3得到的所述第三溶液水浴加热至50～70℃，保温0.5～2h，得到先驱体溶液。本发明制备的先驱体为含碳、钽元素的稳定有机化合物，可长期保存，制备工艺简单、生产成本低，最终获得的TaC陶瓷纯度高。
