Name:
After Professor Vojtĕch Rosický (30 October 1880 Prague, Austria-Hungary – 9 February 1942 Mauthausen, Nazi Germany), former Director of the Mineralogical and Petrological Institute of Masaryk University, Brno, Czech Republic.
Polymorph of:
Sulphur Group.
The densest form of solid S. Can be prepared by slowly cooling molten sulfur that has been heated above 150°C.
Dimorphous with both native sulphur (α-sulphur), to which it changes in time at room temperature, and β-sulphur (clinosulphur).
