摘要
研究了碱土金属氧化物对高铝瓷烧结性质的影响,发现碱土金属氧化物增加高铝瓷韧性的同时并不降低其机械强度。加入不同的碱土金属氧化物其晶粒长宽比不同,一般来讲高长宽比的坯体有较高的韧性和机械强度及韦伯模数。
The effects of alkaline-earth oxides on the sintering properties of high-alumina ceramics were studied in the paper.The experimental results show that the mechanical strength was not decreased with the increase of toughness by adding alkaline-earth oxides in high-alumina ceramics;the aspect ratios of grains was different by adding different alkaline-earth oxides;gerenally,the body with high aspect ratios has high toughness,strength and Weibull modulus.
