摘    要:研究了MgO-CaO系耐火材料中主要氧化物CaO和MgO在高温下的晶粒生长动力学,发现CeO2的存在降低了CaO和MgO的晶粒生长活化能,提高了结构基元的扩散速率,促进了CaO和MgO晶粒的生长,从而揭示了掺CeO2的MgO-CaO系耐火材料抗水化性提高的本质

关 键 词:MgO-CaO材料;动力学;氧化铈

Abstract:The grain growth kinetics of CaO and MgO which are major oxide in the MgO CaO refractories systems is investigated.It was found that the presence of CeO 2 accelerates the grain growth of CaO and MgO by decreasing the activation energy of CaO and MgO and increasing the diffusion rate of structure unit,thus the essence of hydration resistance improving in MgO CaO refracories doped with CeO 2 is revealed.
Keywords:MgO CaO material  kinetics  ceria
