Sulfur is a pale yellow, odorless, brittle solid that is insoluble in water but soluble in carbon disulfide. In every state, whether gas, liquid or solid, elemental sulfur occurs in more than one allotropic form or modification; these present a confusing multitude of forms whose relations are ...

One of the most familiar sulfur compounds is hydrogen sulfide, also known as sulfureted hydrogen, or stinkdamp, H2S. It is the colourless, extremely poisonous gas responsible for the characteristic odour of rotten eggs. It is produced naturally by the decay of organic substances containing sulfur...
1.Also,esp. Brit.,sulphur.a nonmetallic element, ordinarily a flammable yellow solid, of widespread occurrence in combined form, as in sulfide and sulfate compounds and cellular protein: used esp. in making gunpowder and matches, in medicine, and in vulcanizing rubber.Symbol:S;at. wt.:32.064...
The role of solid-gas interactions in air pollution. Final report November 1973--February 1977 Sulfur dioxide and other sulfur-containing gases were studied to evaluate their interactions with solids likely to be found in urban aerosols and on ground... HS Judeikis,TB Stewart,AG Wren,... 被...
Precipitated sulfur is in form of very fine, pale yellow, amorphous or microcrystalline powder /Pharmaceutical/Yellow solid or amber-colored molten liquid.Pure sulfur exists in two stable crystalline forms, alpha and beta, and at least two amorphous (liquid) forms. Alpha-sulfur: rhombic, ...

It was observed that S was frequently found to be collocated with Ni, with higher concentrations being located on or near the surface of the Ni particles exposed to gas, while little S was found near the YSZ phase. 展开 关键词: Anodes Cermets Solid oxide fuel cells Sulfur ...
We estimate that ascending magmas fractionate ~1300 ± 720 ppm S2− as iron sulfide, equivalent to ~0.36 ± 0.20 wt% FeS, with a solid:liquid sulfide ratio of ~0.97:0.03 constrained by the observed Cu/Au ratio (and within error of the Cu/Ag ratio) in the silicate melt...
This leads to it having excellent dielectric properties; indeed the dielectric strength of sulfur hexafluoride gas is about 2.5 times more than that of air. SF6 has therefore been used as an insulating material in electrical systems, as a circuit breaker, in high voltage switch gear and as an...
