Development of Certified Reference Materials for Specific Surface Area of Carbon Black
摘要
Abstract
The three commercial carbon blacks were used as the candidates for certified reference materials (CRMs) of specific surface area and subpackaged in the transparent glass bottles sealed with screw cap by means of cross riffling method. The homogeneity and stability tests showed that the carbon black CRMs were homogeneous and stable for at least 18 months,respectively. The BET specific surface areas of 104.6, 29.9, 8.96 m2/g were certified by internationally recognized nitrogen physical adsorption method among eight validated separate laboratories. Compared with the similar CRMs in the world, it was showed that the uncertainties (2.1％, 2.3％ and 3.2％) of three carbon black CRMs came up to advanced world level.关键词
