Normally, the molecular structure in this group is hard to separate without heating or blending with other additives.
Therefore, to break the semi-solid liquid molecule structure, high temperature is needed.

Cooling of a sulfide melt by granulation leads to the formation of an ultra-dispersed structure, stabilization of high-temperature nonstoichiometric phases, a decrease in the proportion of the metal component, up to its complete elimination, and a significant increase in the reaction surface [14].
