Toughened mullite ceramic and preparation method thereof
The invention discloses toughened mullite ceramic and a preparation method thereof.The toughened mullite ceramic is prepared from, by weight, 80-120 parts of ceramic blank, 20-40 parts of kaolinite, 8-20 parts of hydromuscovite, 4-8 parts of mullite fiber, 6-12 parts of aluminum oxide particles, 14-24 parts of attapulgite and 6-12 parts of graphene, and relates to the technical field of ceramic materials. The mechanical property of the ceramic is improved by adopting a method of adding mullite, the mullite is uniformly added into the ceramic material, and the mullite is used as a toughening phase of a matrix, so that the fracture toughness and the relative strength of the composite material are remarkably enhanced.
本发明公开了一种增韧莫来石陶瓷及其制备方法，由以下重量份组成，陶瓷坯料80‑120重量份、高岭石20‑40重量份、水白云母8‑20重量份、莫来石纤维4‑8重量份、氧化铝微粒6‑12重量份、凹凸棒石14‑24重量份和石墨烯6‑12重量份，本发明涉及陶瓷材料技术领域。本发明采用添加莫来石的方法提高陶瓷的力学性能，将莫来石均匀添加到陶瓷材料中，其中莫来石作为基体的增韧相，显著增强了复合材料的断裂韧性和相对强度。
