Density Measurement - Mettler Toledo


Bulk density is not a property of the material itself. Bulk density includes the spaces between the particles or items as well as any voids within the items themselves. Bulk density can vary depending on how the material is handled; shaking a container, for example, allows parts to settle, increasing the overall bulk density.

Structural and Electrical Conductivity Studies in Nickel ...


density, bulk density, and porosity were calculated. The temperature dependence of the electrical conductivity plot shows the kink, which can be attributed to ferromagnetic-paramagnetic transition. The activation energy obtained from resistivity plots in paramagnetic region is found to be more than that in ferrimagnetic region. The conduction ...
