Sulfides generally oxidize readily in moist air at ambient temperature or in dry air at elevated temperature. Some sulfides possess semi-metallic character and have potentially valuable electronic properties. Rare earth sulfides are semi-conductors and have been used in thermoelectric devices. Alkaline earth sulfides plus those of calcium and zinc are used for phosphor compositions. Molybdenum and tungsten sulfides are widely used, non-graphitic commercial lubricants.
Small lots are promptly available from stock for experimental or test purposes.
Production quantities of many sulfides are also available from stock. Large amounts of other sulfides are produced to customer's specification for rapid shipment. Please contact our sales department with your exact specifications. For example, phosphor, battery and pigment applications usually require fine powders while numerous thin film applications require the use of sputtering targets or evaporation materials. The scope of sulfide applications is continually changing and evolving.
