They cover crystal density, the heat of formation, melting point, the enthalpy and entropy of fusion, the heat of sublimation, impact sensitivity, electric spark sensitivity, shock sensitivity, friction sensitivity, heat sensitivity, and relationships between different sensitivities.
In order to evaluate the surface activity of the elements in molten iron the calculations, using such criteria as melting temperature, surface energy, specific heat of sublimation, entropy in the standard condition, statistic generalized moment, total electron potential barrier for iron and addition have been carried out.
Therefore, throughout this phase, the product will remain colder than the temperature of the shelf that is supplying the heat of sublimation. At the end of primary drying, the product temperature will rise asymptotically toward the shelf temperature.
