Basic dataStandard ID: GB/T 13221-2004 (GB/T13221-2004)Description (Translated English): Nanometer powder. Determination of particle size distribution. Small angle X-ray scattering method Sector / Industry: National Standard (Recommended) Classification of Chinese Standard: N78 Classification of International Standard: 19.120 Word Count Estimation: 12,195 Date of Issue: 2004-09-29 Date of Implementation: 2005-04-01 Older Standard (superseded by this standard): GB/T 13221-1991 Quoted Standard: ISO 9276-1; ISO 9276-2 Adopted Standard: ISO/TS 13762-2001, MOD Regulation (derived from): Announcement of Newly Approved National Standards No. 10 of 2004 (No. 72 overall) Issuing agency(ies): General Administration of Quality Supervision, Inspection and Quarantine of the People Republic of China, China National Standardization Administration Committee Summary: This standard specifies the use of X-ray small-angle scattering effects side be satisfied wood wooden Du degree distribution method. This standard applies to the determination of capsules size I nm ~ 300 nm in the range of particle size distribution of the powder, the inorganic, organic and biological macromolecules off glue determination of particle size, but also for implementation. When a deviation from the spherical shape of the powder particles, the method gives the equivalent spherical diameter of the scattering. This method does not apply to shun grains composed of different materials mixed powder, generally does not apply to a powder emblem holes exist, but emblem nanoscale pore size and smooth grain (or frame) size is 0. 5 ��m or more, can be used to set the appropriate pore size distribution side.
