Method for solidifying a mass of liquid sulfur and relative solid sulfur block obtainable with said method

The present invention relates to a method for solidifying a mass of liquid sulfur comprising the following operative phases: (a) pouring a mass of liquid sulfur into a solidification pond and forming a layer of sulfur which spreads over the surface onto which it is poured at a spreading rate ranging from 1 to 10 cm/s, preferably from 1 to 5 cm/s, and interrupting said pouring when said layer of sulfur has reached a thickness ranging from 5 to 12 cm, preferably from 7.5 to 10 cm; (b) cooling said layer of sulfur until the temperature of its upper surface is lower than or equal to 65 DEG C, more preferably equal to or lower than 60 DEG C, and forming a block of solid sulfur. The present invention also relates to a monolayer or multilayer block of solid sulfur which can be obtained with the above method, in addition to portions of solid sulfur which can be obtained by cutting the above blocks.
