Abstract
A method of transforming a molten material or melt into discrete solid particles comprises forming the melt into prills by passing the melt through a perforated member, dropping the prills onto a bed of powdered material, such as silica flour, to coat the prills with the material in the bed and permitting the prills to cool, thereby to solidify into discrete solid particles. In one embodiment, the melt comprises at least two components such as elemental sulphur and an olefinic hydrocarbon, which are subjected to a chemical reaction, such as the polymerization of the olefinic hydrocarbon with the sulphur to form a sulphur polymer stabilizer. A method of producing a sulphur concrete incorporating the sulphur polymer stabilizer is also provided.
