摘要
为了增进对Al2O3抗热震陶瓷发展动态的了解,为Al2O3抗热震陶瓷的制备提供设计依据,针对Al2O3抗热震陶瓷的常用抗热震性测试方法,Al2O3陶瓷微观结构、表面条件、尺寸对抗热震性的影响,利用第二相法提高Al2O3陶瓷抗热震性的可行性,以及多孔Al2O3抗热震陶瓷的研究进展等方面进行了评述.在Al2O3陶瓷中添加ZrO 2、稀土化合物、低热膨胀系数组元或高热导率组元等可以改善Al2O3陶瓷的抗弯强度、断裂韧性、弹性模量等力学性能和(或)热膨胀系数、热导率等热学性能,从而起到提高Al2O3陶瓷抗热震性能的作用.叠层Al2O3复合抗热震陶瓷将成为今后的一个研究方向.
In order to better understand the development trend of Al2O3 thermal shock resistant ceramics and to provide design consideration for the preparation of Al2O3 thermal shock resistant ceramics,the commonly used thermal shock resistance test methods for the Al2O3 thermal shock resistant ceramics,the influence of microstructures,surface conditions and geometric dimensions of Al2O3 ceramics on the thermal shock resistance,the feasibility of second phase method to improve the thermal shock resistance of Al2O3 ceramics and the research progress on porous Al2O3 thermal shock resistant ceramics,were reviewed.Through the addition of ZrO 2,rare earth compounds,low thermal expansion coefficient components or high thermal conductivity components,some mechanical properties of Al2O3 ceramics,e.g.bending strength,fracture toughness and elastic modulus,can be enhanced,and as well as(or)the thermal properties of Al2O3 ceramics,such as thermal expansion coefficient and thermal conductivity,so as to improve the thermal shock resistance of Al2O3 ceramics.Furthermore,laminated Al2O3 composite thermal shock resistant ceramics will become a research direction in the future.
