Ceramic Density Computation

To compute for theoretical density of ceramics five essential parameters are needed and these parameters are number of formula units in unit cell n sum of atomic weights of atoms σa c sum of atomic weights of anions σa a unit cell volume v c and avogadro s number n a.

It is possible to access the bulk density of a porous ceramic sample by the archimedes method either by immersing a coated sample in a wetting liquid. The image above represents theoretical density of ceramics.

Zro 2 which forms the matrix of this solid solution is a fluorite so final formula should be of the form ao 2 though the ratio will not be exactly.
