Sulfur oxide (SOx) means that these molecules are formed during oxidation reactions involving sulphur and oxygen. E.g.: SO2 emissions are generated primarily from the smelting of ore and fuel combustion.
SOx refers to one or more of the following:
- Lower sulfur oxides (SnO, S7O2 and S6O2)
- Sulfur monoxide (SO)
- Sulfur dioxide (SO2)
- Sulfur trioxide (SO3)
- Higher sulfur oxides (SO3 and SO4 and polymeric condensates of them)
- Disulfur monoxide (S2O)
- Disulfur dioxide (S2O2)
Sulfur Oxide is sometimes spelled as Sulphur Oxide
