How do you find void fraction in a certain ceramic powder (In my case a 50% Al2O3 and 50% YSZ) powder?

13 February 2024 1 10K Report

I would like to know the void fraction for known powder material properties to estimate a bisque sample's packing density/void fraction. In combination with any geometric &/or Archimedes measurements.

Assuming the density of powder to be 5.03 g/cm3 (correct me if I'm wrong)

This is regarding my research.

I appreciate any help you can provide.

Hello!

It's very simple!

It would be best if you weighed a recipient full of powder. Normally, in powder metallurgy, it is a recipient of 100ml which is filled to the brim (the excess must be scraped off), being careful not to pack the powder.

You made this several times (at least 5) and that's it!
