Both Iron Disulfide powders have an average particle size of 2.5 um and a crystallite size of 60nm and 21nm respectively, as determined from x-ray line broadening using the Debye-Scherrer equation. A typical x-ray trace is shown below:

Iron Disulfide is an important material for Li/Si/FeS2 thermal batteries for short duration, high energy applications and Li/FeS2 lithium-ion batteries where an increased run time for high power applications is of benefit. To further enhance these characteristics, Lorad scientists have developed a novel process for the large-scale manufacturing of a nano-structured Iron Disulfide. This nano-structured powder has a higher surface area than other commercially available Iron Disulfide powders giving it a superior rate capability in comparison. Lorad's process also allows for the modification of the particle size to meet particular application requirements. Further, this material is also available with enhanced electric conductivity.
Iron Disulfide is available in large-scale commercial quantities. Please inquire for pricing and availability.
