Abstract
The present invention relates to a process for the preparation of articles of manufacture made of or based on sulphur, which comprises cooling of liquid sulphur in a volume of containment until the sulphur mass solidifies and forming of the product, characterized in that elastic pressure waves are applied to the cooling mass of liquid sulphur to produce a crystalline suspension of solid sulphur in liquid sulphur.

Process for the preparation of an article of manufacture made of, based on or coated with sulphur, which comprises the following steps:
- a) feeding of a mass of liquid sulphur into a volume of containment or forming container of said article of manufacture;
- b) cooling of said mass of liquid sulphur and simultaneous application of elastic waves to said mass of liquid sulphur until a mass of solid crystalline sulphur in suspension in said mass of liquid sulphur is obtained;
- c) finishing of said article of manufacture made of, based on or coated with sulphur following complete solidification of the mass of liquid sulphur.
