The sphalerite composition is favored at 298k by 13kJ/mol, but at 1296K the transition to wurtzite happens.3 Amorphous or "plastic" sulfur is made by immediate cooling of molten sulfur—for instance, by pouring it into cold h2o. X-ray crystallography experiments display that the amorphous form can have a helical construction with https://edgarspibs.tokka-blog.com/27935120/about-infrared-zinc-sulfide
