...Given the correlation between porosity and interpaticle coordination cn, these expression can be rewritten in terms of cn to highlight the relevance of contacts on thermal conduction (for example: cn = 12(1 − n); other correlations can be found in [17])....

...Published studies show that the minimum porosity can be obtained for a mass fraction of small particles FRmass ∼ 30–40%, and that the larger size ratios FRd = Dlarge/Dsmall produce lower porosity and higher mixture density [16,17]....
