Abstract: Sintered metal porous materials are a special type of metal material that integrates structure and function. They are widely used in industries such as coal chemical, petrochemical, aerospace, new energy, semiconductor, smelting, and environmental protection, and play an important role in the development of the national economy This paper introduces the types of sintered metal porous materials and elaborates on their applications in filtration and separation, fluid distribution control, catalytic loading, and enhanced mass and heat transfer. It predicts the development trend of sintered metal porous materials, which will continue to develop towards material composite, pore size refinement, structural gradient, widespread application, and multifunctionality in the future.
