Description
技术领域
本发明属于高温结构功能一体化陶瓷的技术领域,涉及一种可在超高温环境中使用的高强度氮化硼陶瓷的制备方法。
背景技术
六方氮化硼(h-BN)陶瓷便是一种有着巨大发展潜力的高温结构陶瓷材料。h-BN是一种具有类似石墨结层状结构的新材料,呈象牙白色,故俗称“白石墨”,其无明显熔点,且在高温下无软化现象,耐强酸强碱腐蚀。h-BN耐热性非常好,可以在900℃以下的氧化氛围中和2800℃以下的氮气和惰性气氛中使用。同其它陶瓷材料相比,h-BN陶瓷具有耐高温、高热导率、膨胀系数低、抗热震等一系列特性,是一种性能优异的高温结构陶瓷材料,在各个领域被广泛应用。目前六方氮化硼陶瓷也存在的一些问题:h-BN粉末具有松散、易吸潮等性质,热压烧结陶瓷致密度低,机械强度比较低,具有较明显的各向异性、且在氧气气氛中稳定性比较差,使用温度在900℃以下[1,2]。
其他专利则是通过加入第二相,来强化氮化硼基陶瓷的各项性能[3,4]。本发明研究了可在超高温环境中使用的高强度氮化硼陶瓷的制备方法,在保证氮化硼陶瓷高温性能的同时,提高了传统氮化硼陶瓷的力学性能,解决了氮化硼粉体细化与潮解氧化的矛盾,降低了高强氮化硼陶瓷材料的生产成本。
