The standard method of Measuring for true density of powder

The principle of powder true density is measure the true powder volume by adopting the Archimedean principle, and then according to the powder mass to calculating the true density of powder. The measuring key of powder true density is testing the true volume of powder. The most important for testing powder true volume is exhaust the bubbles between pores of powder. It is a very accurate method to measuring powder or particle density by pycnometer method.

The testing technique summary of powder true density:

The powder true density is the ratio of powder weight to true volume.

True volume excludes the closed space in powder particles. Therefore, the pore-free material can be used to testing the powder true density.

According to different measuring medium, powder true density also has the different measuring method.

Generally speaking, it can be classified as gas volume method and immersion method.
