Abstract: h-BN has excellent thermal shock resistance and chemical stability.It has a graphite-like layered structure and is widely used in metallurgy,chemical industry,electronics and other fields.The research and application of h-BN in refractories were reviewed,including the improvement of the thermal shock resistance,oxidation resistance,and slag resistance of refractories by h-BN,as well as its effect on the sintering properties of refractories.The application of hot-pressed sintered h-BN composites in key components of iron and steel metallurgy and the improvement measures of the mechanical properties,thermal shock resistance,oxidation resistance and corrosion resistance to molten steel were summarized.The problems existing in the application of h-BN in refractories and high temperature ceramics for metallurgy were pointed out.

Key words: h-BN, graphite, thermal shock resistance, oxidation resistance, slag resistance, corrosion resistance to molten steel
