Abstract

The present invention intends to provide a method by which the scattering property of a powder can be more clearly evaluated. There is provided a method for evaluating a scattering property of a powder, the method including dropping a powder to be evaluated onto a liquid placed in a box, thereby scattering the powder as dust in the box, and measuring a dust concentration in air in the box with a dust meter. There is also provided an apparatus for evaluating a scattering property of a powder, the apparatus including a box in which a liquid is to be placed, and a dust meter that measures a dust concentration in air in the box when the powder to be evaluated drops onto the liquid placed in the box and scatters as dust.
