標準簡介
This Standard specifies method for the particle size determination in metal catalysts such as supported metal catalysts by electron microscope. This standard specifies the test specimen of particle diameter from 1 nm to 100 nm for transmission electron microscope, and the particle diameter from 2 nm to 100 nm and metal contents 0.1 % or over for the test specimen of scanning electron microscope.
