摘要
在方镁石 -尖晶石耐火材料中 ,加入三种不同类型的含ZrO2 添加剂 ,均能明显提高材料的力学性能。经XRD、偏光显微镜及电子探针分析 ,认为改善性能的机理在于 :引入ZrO2 改善了材料的显微组织结构 ,并产生了适量微裂纹 ,强化了基质 。
Effect of three kinds of ZrO 2 bearing additives on properties of periclase spinel refractories has been researched, and the effect mechanism has been analyzed by means of XRD, polarizing microscope and electron probe. The results show that all the additives could improve the mechanical properties of the materials because the added ZrO 2 has optimized the microstructure, introduced appropriate amount of micro cracks and enhanced the matrix.
