The invention discloses a CNT-B4C-TiB2 composite ceramic and a preparation method thereof, and belongs to the technical field of composite material preparation. The preparation method of the CNT-B4C-TiB2 composite ceramic comprises the following steps: S1, a CNT dispersion liquid is mixed with B4C, TiO2 and phenolic resin, and uniformly stirring is performed to obtain CNT-B4C-TiO2 composite slurry; S2, the CNT-B4C-TiO2 composite slurry is subjected to spray granulation, and CNT-B4C-TiO2 composite dry powder is obtained; and S3, the CNT-B4C-TiO2 composite dry powder is laid in a mold, and blankpressing and forming are conducted; and then, firing is performed to obtain the CNT-B4C-TiB2 composite ceramic. By adding the CNT and adopting a staged sintering process, the toughness and hardness of the prepared composite ceramic can be improved while the sintering requirement is reduced.
一种CNT‑BC‑TiB复相陶瓷及其制备方法，属于复合材料制备技术领域。该CNT‑BC‑TiB复相陶瓷的制备方法包括以下步骤：S1，将CNT分散液与BC、TiO、酚醛树脂混合，搅拌均匀得到CNT‑BC‑TiO复合浆料；S2，CNT‑BC‑TiO复合浆料经过喷雾造粒，获得CNT‑BC‑TiO复合干粉；S3，将CNT‑BC‑TiO复合干粉铺设在模具中，压坯成型；之后烧制得到CNT‑BC‑TiB复相陶瓷。本发明通过添加CNT并采用分阶段烧结的工艺，在降低烧结要求的同时能够提高制成的复相陶瓷的韧性和硬度。
