Abstract: The certified reference materials for specific surface area, pore structures of porous and highly dispersed materials play an important role in instrument calibration, method validation and product quality control, etc. The principles of determining specific surface area, pore structures of porous and highly dispersed materials by using physisorption and mer cury intrusion methods were briefly introduced, including the present sit uation of some corresponding analytical standards. The overseas present status of certified reference materials for specific surface area, pore struc tures of porous and highly dispersed materials by using physisorption and mercury intrusion methods were also discussed, and the shortcomings and some suggestions on developing our these certified reference materi als were indicated. 

Keywords: porous and highly dispersed materials; specific surface area; pore structures; certified reference materials
