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.

The image above represents theoretical density of ceramics. 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 calculation of the density of this solid solution is more difficult than the previous calculations because the chemical formula must be determined before the formula mass can be calculated. 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.
