Process for the preparation and analysis of a powder by means of instrumental analysis and use

摘要

The invention relates to a method for preparing and examining a powder by means of instrumental analysis, comprising the steps: generating at least one two-dimensional image (SEM, 6) of an initial small amount (4) of powder grains (43) of the powder (2); Determining and outputting at least one primary powder grain structure parameter (14) based on the at least one two-dimensional pictorial representation (6) of the initial small amount (4); A production (200) of a solid body (10), having a statistically validatable powder representation (5) of the totality of the powder grains from the powder (2); A pictorial representation (CT, 30) of the solid body (10), at least one imaging parameter and / or at least one image recording setting being adapted based on the at least one initial powder grain structure parameter (23); Determining and outputting at least one parameter (20) of the statistically validatable powder representation (5) of powder grains (44) of the powder (2) by evaluating the at least one pictorial, in particular computer tomographic representation (CT, 30) of the solid body.
