Densities from crystallographic information

Calculating Densities/Concentrations from Crystallographic Information... 

In a proper catalytic study, as much as possible should be learned about the physical properties of the catalyst employed. These properties include the total surface area of the catalyst, the average pore size and/or the pore size distribution, the metal surface area and average metal crystallite size, especially in supported metal catalysts, as well as the metal weight loading of the latter. From this information and the packing densities of different crystallographic planes, one can calculate the dispersion of the metal. Dm, defined as the fraction of the total amount of metal atoms, Nm(, that exist as surface atoms, Nm, thus.
