Sulphur is an odorless, tasteless, light yellow solid. It is a reactive element that given favorable circumstances combines with all other elements except gases, gold, and platinum. Sulfur appears in a number of different allotropic modifications: rhombic, monoclinic, polymeric, and others. The rhombic structure is the most commonly found sulfur form. Each allotropic form differs in solubility, specific gravity, crystalline, crystalline arrangement, and other physical constants. These various allotropes also can exist together in equilibrium in definite proportions, depending on temperature and pressure. Sulphur is excellent in situations where burning sulphur is required in production processes. Recommendations are based on each individual Industrial process requiring a pure sulphur ingredient.
