Daily Science – Why is the weight of silicon carbide carriers of the same mesh size and volume different?

Differences in the weight of silicon carbide (SiC) carriers of the same mesh size and volume may occur and are mainly influenced by the following factors:

Porosity – high pore structure reduces the density of the material;

Additives – binder or reinforcing phases change the overall specific gravity;

Microstructure – grain size and sintering process affect the degree of densification;

Catalyst coatings – noble metal or oxide loading increases mass;

Manufacturing deviations – dimensional tolerances and sintering shrinkage cause small fluctuations.
Together, these variables determine the physical properties of the final product.
