DIFFUSION STATE EVALUATION POWDER, METHOD FOR EVALUATING DIFFUSION STATE OF POWDERY MATERIAL, AND METHOD FOR EVALUATING MEANS FOR PREVENTING DIFFUSION OF POWDERY MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a diffusion state evaluation powder which can sensitively and qualitatively confirm the scattering state of powdery material in a predetermined region and can also make a rapid and efficient quantitative evaluation of the scattering state, a method for evaluating the diffusion state of powdery material using the diffusion state evaluation powder, and a method for evaluating means for preventing diffusion of powdery material.;SOLUTION: The present invention relates to powder for evaluating the diffusion state of powdery material as complex powder obtained by attaching powder of material which emits fluorescence by ultraviolet radiation to at least a part of the surface of powder of a compound selected from the group of adenosine 5'-triphosphoric acid and derivatives thereof, and relates to application of the powder.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
