High-toughness silicon nitride ceramic and preparation method thereof
The invention relates to high-toughness silicon nitride ceramic and a preparation method thereof. The high-toughness silicon nitride ceramic is obtained through sintering by taking Si3N4 as a main phase, taking at least one of SiC fibers, carbon fibers, graphene, carbon nanotubes and YB2C2 as a second phase and taking metal oxide and rare earth oxide as sintering aids.
本发明涉及一种高韧性氮化硅陶瓷及其制备方法，所述高韧性氮化硅陶瓷是以SiN作为主相，以SiC纤维、碳纤维、石墨烯、碳纳米管和YBC中的至少一种作为第二相，以及金属氧化物和稀土氧化物作为烧结助剂，经过烧结后得到。
