This study shows that transmission electron microscopy (TEM) can be applied to industrial and semi-industrial cokes. TEM provides an experimental method that is complementary to optical microscopy. The scientific results are as follows: - TEM makes distinctions never previously possible between various cokes. It reveals invisible differences between cokes from different coals particularly of a low order. - The microtexture of cokes coming from binary mixes can be calculated by addition of the microtextures of the constituents. - TEM can explain the relationships between microtexture and certain industrial properties of cokes such as carboxy-reactivity and the electrical resistivity. These results suggest the use of this technique for the detailed study of industrial cokes and the prediction of their properties.
