By Ming Wah Wong (auth.), Ralf Steudel (eds.)

Despite greater than 2 hundred years of sulfur examine the chemistry of elemental sulfur and sulfur-rich compounds continues to be packed with “white spots” that have to be crammed in with reliable wisdom and trustworthy information. this example is parti- larly regrettable for the reason that elemental sulfur is without doubt one of the most vital uncooked - terials of the chemical produced in record-breaking amounts of ca. 35 million lots each year world wide and usually used for the creation of sulfuric acid. thankfully, huge, immense growth has been made over the past 30 years within the knowing of the “yellow element”. because the results of broad inter- tional study actions sulfur has now develop into the aspect with the most important variety of allotropes, the aspect with the most important variety of binary oxides, and likewise the aspect with the biggest variety of binary nitrides. Sulfur, a regular non-metal, has been chanced on to develop into a steel at excessive strain and is even superconducting at 10 ok below a strain of ninety three GPa and at 17 okay at 260 GPa, respectively. this is often the top severe temperature of all chemical parts. really, the pressure-temperature part diagram of sulfur is without doubt one of the most complex of all parts and nonetheless wishes extra investigation.
