Determination of coefficient of friction between two spherical particles

In summary, the coefficient of friction between two spherical particles is a measure of resistance to motion and can be determined through experimental methods. Various factors can affect this coefficient, and it is important to determine it in order to understand and predict system behavior. Additionally, the coefficient of friction can be changed by altering surface properties, pressure, or introducing lubricants or additives.

I have some very small spherical particles with diameter of 1 mm and i would like to know coefficient of friction between them. Can anyone suggest an experiment/device that would help me?

In order to get friction between a plate and particle i can use tilt test and measure the angle at which a group of connected particles slips.

maybe glue a bunch on piece of paper then slide them down a plane made of that material , and use the tilt test like you said.
