Sulfide compounds are salts or esters of sulfuric acid formed by replacing one or more hydrogen ions with a metal. Many sulfate compounds are readily soluble in water or acidic solutions and also have some organic or organometallic properties. Sulfide compounds may be useful in the development of water treatment and fuel cells, whereas some are soluble in organic solvents for a wide variety of applications.
Platinum ii sulfide formula
The chemical formula of platinum ii sulfide is PtS2 and its molecular weight is 307. It is a black, semi-conducting solid and is highly resistant to corrosion. It can be dispersed utilizing suspended or coated nanoparticles, and deposited by sputtering targets and evaporation materials.
Empirical parameterizations of partition coefficients between mss and sulfide melt are summarized in Table 2. These results indicate that PGE, Ni, and Cu are compatible with mss at high temperatures (equilibrium crystallization), but as temperature decreases, the DNi increases to approach 1.
During equilibrium crystallization of mss from a massive sulfide orebody, fractionated sulfide liquids migrate away from the cumulates. These low sulfide liquids are usually enriched in IPGE and contain a higher concentration of copper than the cumulates themselves. These sulfide liquids are also characterized by a small percentage of iron and a significant amount of nickel.
