The sphalerite structure is favored at 298k by 13kJ/mol, but at 1296K the transition to wurtzite takes place.3 Amorphous or "plastic" sulfur is made by immediate cooling of molten sulfur—for instance, by pouring it into chilly h2o. X-ray crystallography research clearly show the amorphous variety may have a helical construction https://mariong158fpx3.wikiadvocate.com/user
