Welcome to ourNCNST

On Nov.16th 2009, nano-Al₂O₃ reference material (RM) for specific surface area (SSA) produced by National Center for Nanoscience and Technology (NCNST) was approved as primary RM by General Administration of Quality Supervision, Inspection and Quarantine of China. “The State Certificate for the Gradation of Certified Reference Materials” and “Licence for Manufacturing Measuring Instruments” were awarded. This RM composed of nanomaterials was the first primary RM for SSA in China, and its relative uncertainty was lower than the similar RMs issued by other organizations, such as National Institute for Standards and Technology (NIST), Joint Research Center (JRC), etc.. The nano-Al₂O₃ RM, which could be used for calibrating instruments and providing authoritative measurement data, not only filled the gaps of high SSA RMs in the world, but also was of great significance in enhancing international competitiveness of nano-industry in China and breaking through the trade barriers in developed countries.

The Certified Reference Materials No.: GBW13901; the certified value: 445.4 m²/g, uncertainty: 5.8 m²/g; “Licence for Manufacturing Measuring Instruments” No.: 10000973.
