Refractories are important supporting materials for high-temperature industry. With the continuous development of related technologies, a large amount of literature has been accumulated. However, it is difficult to read so much literature with traditional methods, and it is more difficult to further analyze and summarize them. Therefore, in the past, personal experience was often based on selecting representative literature for summary and analysis. However, this method is difficult to have a comprehensive, quantitative and in-depth analysis and induction of research trends, which is not conducive to systematically grasp its development status and trends, and has gradually become difficult to meet the future needs of scientific research. This work summarizes the current situation of refractory research from the perspective of knowledge graph. By using CNKI and WOS (Web of Science) core database, the overall development venation of refractory research from the scope of China and the world is introduced, and the research hotspots and trends in the field of carbon containing refractories are introduced. At last, the future development of refractories and knowledge map has prospected.
