Ceramic material with high fracture toughness as well as preparation method and application of ceramic material
The invention belongs to the technical field of ceramic material preparation, and relates to a ceramic material with strong fracture toughness and a preparation method and application of the ceramic material. The ceramic material comprises the following raw materials by volume percentage: 55-75% of alpha-Si3N4, 5-15% of TiC, 0-15% of ZrSi2, 0-15% of nano h-BN@SiO2, 3-7% of Al2O3 and 5-7% of Y2O3, and the nano h-BN@SiO2 is not 0. The h-BN@SiO2 with the nano core-shell structure and a matrix material form an intragranular structure, so that the fracture toughness is greatly improved.
本发明属于陶瓷材料制备技术领域，涉及一种断裂韧性强的陶瓷材料及制备方法和应用，所述陶瓷材料包括：按照各原料组分的体积百分数：α‑Si3N4 55‑75％，TiC 5‑15％，ZrSi2 0‑15％，纳米h‑BN@SiO2 0‑15％，Al2O3 3‑7％，Y2O3 5‑7％，其中，纳米h‑BN@SiO2不为0。通过纳米核壳结构的h‑BN@SiO2与基体材料形成晶内型结构，极大的提高断裂韧性。
