JIS H 7803:2005 English Edition

General rules for the determination of particle size and crystallite size in metal catalysts

Abstract

This Standard specifies the common items to measure the particle size dispersed in metal catalysts by electron microscope method, and the crystallite size in metal catalysts by X-ray diffraction method, consisting of metal elements of the particle diameter from 1 nm to 100 nm existing on the carrier in a dispersed and fixed condition (for example, supported metal catalysts) and in a condition of the metal colloid being independent or dispersed in the medium (for example, metal colloid suspension).
