Molybdenum Sulfide or Molybdenum Disulfide is a moderately water and acid soluble Molybdenum source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy materials and fuel cells. Molybdenum Sulfide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of 95.96. The number of electrons in each of molybdenum's shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d5 5s1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm. In its elemental form, molybdenum has a gray metallic appearance. Molybdenum was discovered by Carl Wilhelm in 1778 and first isolated by Peter Jacob Hjelm in 1781. Molybdenum is the 54th most abundant element in the earth's crust. It has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum does not occur naturally as a free metal, it is found in various oxidation states in minerals. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead.

Sulfur or Sulphur (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne]3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777 when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
